Do states with more guns have higher rates of fatal police shootings? This article uses a validated measure of firearm availability (the percentage of suicides committed with a firearm) to examine the relationship between gun proliferation and fatal police shootings. It expands on existing research to include (1) measures of access to Level I and II trauma centers, (2) interpretation of the findings from the lenses of “statistical prediction,” and (3) tests for structural differences between models for black descendants versus nonblack decedents. Findings confirm the correlation between statewide prevalence of gun ownership and fatal police shootings for both all decedents and unarmed decedents. It provides partial support for “statistical prediction” by police and finds that greater access to trauma centers is associated with lower rates of citizen deaths. The analysis suggests a far broader range of policy options for saving lives, such as better enforcement of legal restrictions on firearm possession, than focusing solely on policing systems.

Importance: The past quarter-century has seen both sharp declines and increases in firearm violence in the United States. Yet, little is known about the age of first exposure to firearm violence and how it may differ by race, sex, and cohort.

Objective: To examine race, sex, and cohort differences in exposure to firearm violence in a representative longitudinal study of children who grew up in periods with varying rates of firearm violence in the United States and to examine spatial proximity to firearm violence in adulthood.

Design, setting, and participants: This population-based representative cohort study included multiple cohorts of children followed-up from 1995 through 2021 in the Project on Human Development in Chicago Neighborhoods (PHDCN). Participants included Black, Hispanic, and White respondents from 4 age cohorts of Chicago, Illinois, residents, with modal birth years of 1981, 1984, 1987, and 1996. Data analyses were conducted from May 2022 to March 2023.

Main outcomes and measures: Firearm violence exposure, including age when first shot, age when first saw someone shot, and past-year frequency of fatal and nonfatal shootings within 250 m of residence.

Results: There were 2418 participants in wave 1 (in the mid-1990s), and they were evenly split by sex, with 1209 males (50.00%) and 1209 females (50.00%). There were 890 Black respondents, 1146 Hispanic respondents, and 382 White respondents. Male respondents were much more likely than female respondents to have been shot (adjusted hazard ratio [aHR], 4.23; 95% CI, 2.28-7.84), but only moderately more likely to have seen someone shot (aHR, 1.48; 95% CI, 1.27-1.72). Compared with White individuals, Black individuals experienced higher rates of all 3 forms of exposure (been shot: aHR, 3.05; 95% CI, 1.22-7.60; seen someone shot: aHR, 4.69; 95% CI, 3.41-6.46; nearby shootings: adjusted incidence rate ratio [aIRR], 12.40; 95% CI, 6.88-22.35), and Hispanic respondents experienced higher rates of 2 forms of violence exposure (seen someone shot: aHR, 2.59; 95% CI, 1.85-3.62; nearby shootings: aIRR, 3.77; 95% CI, 2.08-6.84). Respondents born in the mid-1990s who grew up amidst large declines in homicide but reached adulthood during city and national spikes in firearm violence in 2016 were less likely to have seen someone shot than those born in the early 1980s who grew up during the peak of homicide in the early 1990s (aHR, 0.49; 95% CI, 0.35-0.69). However, the likelihood of having been shot did not significantly differ between these cohorts (aHR, 0.81; 95% CI, 0.40-1.63).

Conclusions and relevance: In this longitudinal multicohort study of exposure to firearm violence, there were stark differences by race and sex, yet the extent of exposure to violence was not simply the product of these characteristics. These findings on cohort differences suggest changing societal conditions were key factors associated with whether and at what life stage individuals from all race and sex groups were exposed to firearm violence.

BACKGROUND AND OBJECTIVES: In 2020, firearm injuries became the leading cause of death among US abstract children and adolescents. This study aimed to evaluate new 2021 data on US pediatric firearm deaths and disparities to understand trends compared with previous years. METHODS: Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research was queried for firearm mortalities in children/adolescents from 2018 to 2021. Absolute mortality, death rates, and characteristics were reported. Death rates were defined per 100 000 persons in that population per year. Death rates across states were illustrated via geographic heat maps, and correlations with state poverty levels were calculated. RESULTS: In 2021, firearms continued to be the leading cause of death among US children. From 2018 to 2021, there was a 41.6% increase in the firearm death rate. In 2021, among children who died by firearms, 84.8% were male, 49.9% were Black, 82.6% were aged 15 to 19 years, and 64.3% died by homicide. Black children accounted for 67.3% of firearm homicides, with a death rate increase of 1.8 from 2020 to 2021. White children accounted for 78.4% of firearm suicides. From 2020 to 2021, the suicide rate increased among Black and white children, yet decreased among American Indian or Alaskan Native children. Geographically, there were worsening clusters of firearm death rates in Southern states and increasing rates in Midwestern states from 2018 to 2021. Across the United States, higher poverty levels correlated with higher firearm death rates (R 5 0.76, P < .001). CONCLUSIONS: US pediatric firearm deaths increased in 2021, above the spike in 2020, with worsening disparities. Implementation of prevention strategies and policies among communities at highest risk is critical

By reviewing studies of how today’s terrorist and extremist groups operate on social media in conjunction with an overview of U.S. government regulation of terrorist content online, this report finds that stricter U.S. regulation of social media providers may not be the most effective method of combating online terrorist and extremist content.

Specifically:

• Direct governmental regulations that ignore other sources of regulation on content removal policies could disrupt growing intra-industry collaboration on countering terrorist content online.

• In many regards, the U.S. government defers to and depends on the private sector to conduct counterterrorism online. Many factors contribute to this arrangement, including limits on the government’s authorities, expertise, staffpower, dexterity and political will to manage online terrorist content with the same efficacy as major social media companies.

• Attempts by other governments to strictly regulate social media companies’ terrorist content removal policies hurt small companies, created double standards and redundancies, and raised concerns about censorship and free speech.

• Proposed regulations may only affect major U.S. social media providers; smaller and non-U.S. companies may be unable, unwilling, or not required to comply. Due to the proliferation of social media platforms exploited by terrorists and extremists, platforms that may be unaffected by U.S. government regulation currently host a large proportion of terrorist content online.

• In certain regards, major social media companies’ content removal policies have more flexibility than the U.S. government to be able to account for new terrorist and extremist groups and actors and their respective tactics, techniques, and procedures online.

The Iraqi Parliament is poised to discuss a new amnesty bill that has generated significant controversy and debate. This legislation is intended to address the issue of wrongful detentions but raises profound ethical, judicial, and societal concerns. Advocates claim the bill will rectify unjust imprisonment, particularly in the post-ISIS era. Critics, however, argue that the bill's broad language could inadvertently release individuals affiliated with ISIS, undermining ongoing counterterrorism efforts and the pursuit of justice for victims. Complicating matters further is the recent decision by the United Nations Security Council to terminate the mandate of UNITAD, a team responsible for investigating crimes committed by ISIS. This article delves into the intricacies of the proposed bill, its implications for justice and national reconciliation, and its potential impact on counterterrorism efforts in Iraq.

Executive Summary • Hamas supporters have long operated in the United States. Internal Hamas documents and FBI wiretaps introduced as evidence in various federal criminal cases clearly show the existence of a nationwide Hamas network engaged in fundraising, lobbying, education, and propaganda dissemination dating back to the 1980s. • The network formalized its existence in 1988, when it created the Palestine Committee in the US. The Committee’s goals included “increasing the financial and the moral support for Hamas,” “fighting surrendering solutions,” and publicizing “the savagery of the Jews.” • The Palestine Committee spawned several public-facing organizations, most of which are based out of Chicago, Dallas, and Washington DC. They included the all-purpose Islamic Association for Palestine (IAP), the financial arm represented by the Occupied Land Fund (which later became the Holy Land Foundation, HLF), and the think tank United Association for Studies and Research (UASR). • In 1993, the FBI wiretapped a meeting of top Hamas activists in the US held in Philadelphia. The wiretaps show internal discussions on how to improve activities in support of Hamas within the US and how to shield them from the designation of Hamas as a terrorist organization. US-based Hamas activists agreed that hiding their affiliation and intentions was the best tactic to avoid negative consequences. “I swear by Allah that war is deception,” said one senior leader, “[d]eceive, camouflage, pretend that you’re leaving while you’re walking that way. Deceive your enemy.” “Let's not hoist a large Islamic flag and let's not be barbaric-talking. We will remain a front so that if the thing [the U.S. government ban on Hamas] happens, we will benefit from the new happenings instead of having all of our organizations classified and exposed.” • Over the years, US authorities have conducted several activities to clamp down on the network, including deporting and prosecuting Hamas operatives and shutting down multiple front organizations. The 2001 designation of HLF and subsequent prosecution of part of its leadership for funneling approximately $12.4 million to Hamas constitutes to date the largest successful terrorism financing prosecution in US history. • Yet, US-based Hamas networks and individuals have displayed a remarkable resilience and many of the core activists of the Palestine Committee are still engaged in various forms of support (albeit at times purely political and not material) for Hamas.

 As the threat from white supremacist and Salafi-jihadist extremists to the United States grew in prominence in recent years, the two movements have become the subjects of several comparative studies. These works frequently focus on contrasting their methods of radicalization, recruitment, use of digital communications technologies, and connections to transnational extremist movements, but only a handful concern their methods of planning attacks on American soil. This report seeks to add to this emerging literature by examining what, if any, relationships there are between the tactics and targets chosen by white supremacist and Salafi-jihadist terrorists in America. In doing so, it will also contribute to our understanding of how, and indeed if, modern terrorists in America are learning from each other or from the current American counterterrorism posture. This report finds that: ● Jihadist and white supremacist attack planners in the U.S. selected different targets for their attacks. Jihadists tended towards attacking “hard targets” (for instance, military bases and law enforcement facilities) and devising plots to assassinate individuals. White supremacists erred towards “soft targets,” especially religious institutions and houses of worship. ● Jihadists were more likely than white supremacists to consider multiple targets for their attacks. ● The tactics of jihadists and white supremacists were relatively similar in frequency to one another. Both movements’ attack plotters relied heavily on plots involving firearms and explosives, but also experimented with non-conventional means such as vehicle rammings, arson, and train derailments. ● Despite some evidence of ideological cross-pollination, particularly in the form of manifestos and instructional material, evidence of direct learning between jihadist and white supremacist attack planners in the U.S. is limited. ● Independent innovation in the face of U.S. domestic counterterrorism approaches is a more likely explanation for similarities in targets and tactics between white supremacists and jihadists than cross-group tactical imitation.

  In the United States, critical infrastructure, or “assets, systems, and networks, whether physical or virtual, [that] are considered so vital to the United States that their incapacitation or destruction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof,” are prime targets in violent extremist attack plots.1 While a variety of violent extremist movements have attempted to assault American critical infrastructure throughout modern history, the Department of Homeland Security and other national security authorities have recently sounded the alarm that U.S.-based violent extremists have developed “credible, specific plans” to attack critical infrastructure.2 To understand the current dimensions of this threat, this paper reviews 94 cases of individuals charged in the U.S. federal court system from 2016 to 2022 with planning to conduct violent extremist attacks, 35 of whom attempted to attack critical infrastructure systems. 19 of these cases are associated with the Salafi-jihadist movement; 16 are associated with white supremacist groups. Evaluating these cases, the report finds: ● Salafi-jihadist attack planners were significantly more likely to consider critical infrastructure systems as targets for attack than their white supremacist counterparts. ● Salafi-jihadist and white supremacist attack planners attempted to target different critical infrastructure sectors, with the former focusing on the commercial facilities, government facilities, and emergency services sectors, and the latter predominantly focusing on the energy sector. ● Since 2019, white supremacist attacks plots against critical infrastructure systems have distinctly increased. ● Between 2016 and 2022, white supremacist plots targeting energy systems dramatically increased in frequency. 13 individuals associated with the movement were arrested and charged in federal court with planning attacks on the energy sector; 11 of these attack planners were charged after 2020. ● The rise of accelerationist ideology and doctrine during the past decade likely fueled the increased risk of attack plots within white supremacist milieus targeting critical infrastructure, and the energy sector in particular.

Nothing puts the human conscience on trial as does the Genocide in Gaza. Nothing illustrates the political hypocrisy of some Western leaders as does the war in Gaza. Nothing exemplifies the double standard of Western political leaders as their complicity in the Gazan war. Moreover, this war has put the International Court of Justice and International Criminal Court in a somewhat difficult and precarious position. It has also put the UNHR in a difficult situation and it is alarmed with the seriousness of atrocities in Gaza. These courts and international organizations are instituted to establish justice and fairness in all international conflicts. They cannot discriminate between countries in their application of justice. They cannot apply one set of laws to the State of Zionist Israel and another set of laws to the people of Palestine. They must do unconditional justice to all parties equally without any prejudice, racial religious, or political discrimination. They must do this to protect the integrity and reputation of these international institutions and yet, the Zionist State of Israel and its supporters are standing between these institutions and their official responsibilities to apply laws equally to all. Take, for instance, the South African lawsuit against the state of Israel for its genocide in the Gaza Strip. Many countries in the Global South welcomed and supported South Africa’s initiative to file a case against Israel and yet, many Western countries blindly dismissed the legal complaint of South Africa in support of Israel as if there was no genocide committed in the Gaza by the State of Israel. To understand the gravity of the political discrimination of some Western leaders on the problem of the Gaza Genocide, we should revisit the contents of the UN’s convention on the prevention of the Crime of Genocide.

The use of improvised explosive devices (IEDs) in West Africa expanded dramatically between 2014 and 2022. As of 2022, Burkina Faso, Cameroon, Mali, Niger, and Nigeria were heavily affected by these weapons, while Benin, Côte d’Ivoire, and Togo suffered from their use as an emerging threat. IED-building networks have established material and training links across conflict theatres in West and Central Africa, including the Lake Chad Basin, where armed groups have used IEDs extensively. IED designs have remained constant and inexpensive throughout the West Africa region, making them attractive for use in attacks against domestic and international security forces, UN peacekeepers, and civilians. The Small Arms Survey collected data on more than 2,200 IED-related incidents between March 2013 and September 2022, including the type, date, and location of these events. Information on perpetrators, their targets, and more than 6,600 casualties from deaths and injuries was also collected (Small Arms Survey, 2022). The data was collected through research undertaken in Burkina Faso, Cameroon, Côte d’Ivoire, Ghana, Guinea, Mali, and Niger, as well as desk research and remote interviews concerning Benin, Chad, and Nigeria. Where relevant from a comparative perspective, discussion of other regions that have countries with IED incidents or components occurs throughout the Report, such as those in North Africa, Central Africa, East Africa, and the Middle East. Most IED incidents analysed during this study involved IEDs containing explosive components or precursors specifically manufactured for the commercial extractive and construction sectors. Chemical products such as ammonium nitrate (AN), manufactured and supplied for bulk mining explosive emulsions, have entered IED-building networks, and are sourced principally from Ghana and Nigeria. Commercial explosives in bulk, including their precursors and accessories such as electric initiators and detonating cords, are diverted from the legal to illicit markets. This diversion primarily fulfils demand from the largely unregulated artisanal gold mining sector across West and Central Africa. A small subset of this diverted material also provisions IED construction. Captured, stolen, and recovered explosive ordnance—including legacy anti-vehicle mines trafficked from Chad, Libya, and possibly Sudan—also constitutes a source of IED components. Coordinated action among affected, source, and transit states is required to prevent armed groups and criminals from accessing commercial explosive materials and other IED components. Such action can involve: national stocktaking exercises; the development of national and regional counter-IED (C-IED) strategies; monitoring, information-sharing, and coordination mechanisms; regulatory modernization and harmonization;  engagement with artisanal mining associations, the mining and explosives industry, states, and regional trade blocs in pursuit of regulatory reform; and efforts to establish minimum standards for bulk and individual traceability of commercial explosives. Reducing the recovery of explosive ordnance requires renewed programmatic investment in clearing minefields and explosive remnants of war across the Sahe

The trafficking of firearms and their use in criminal violence in Europe has received significant attention from researchers and policymakers. Less is known, however, about the illicit proliferation of firearm ammunition and other explosive munitions. Currently, detailed data on illicit munitions in Europe can only be accessed through specialized law enforcement agencies. National seizure statistics often lack the necessary detail for policy-relevant analysis, as do the media reports, which often include incomplete or inaccurate information on the types and calibres of ammunition. 

KEY FINDINGS • Calibres typically associated with handguns and widely available commercial brands of ammunition usually represent the bulk of the illicit firearm ammunition seen in the countries studied. • Illicit firearms ammunition is not necessarily trafficked from abroad, as shown by the misuse of domestically produced cartridges in the five surveyed countries. Moreover, cartridges produced legally within the European Union (EU) have been recovered the same year at crime scenes. • A large percentage of illicit hand grenades and other factory-produced explosive munitions seized in the European countries under review were manufactured in the former Yugoslavia. The seizures are consistent with media reports and government statements indicating that the Balkans are a major source of illicit grenades acquired and used by criminals in the EU. • The number of illicit grenades documented in the Netherlands and Sweden has decreased significantly in recent years, possibly owing to Covid-19-related travel and shipping disruptions, an increased reliance on other types of explosives by criminals, and national and regional counter-trafficking efforts.

This Special Report of the National Institute of Justice (NIJ) presents a synthesis of select findings from over 60 publications on 18 NIJ-supported research projects on public mass shootings, including school mass shootings, since 2014. It also identifies areas of need and interest for future research and recommendations. For the purpose of this report, we define public mass shooting as a shooting event in a public setting that causes at least four fatalities in a single event. Excluded from our definition are events that occur in the course of a separate felony or domestic incident. However, the definition of a mass shooting varies among sources; for more information see “The Challenges of Defining ‘Mass Shooting’” in Part I of this report.

Overdose deaths in North America have soared, primarily because of the spread of illegally manufactured fentanyl. This paper uses detailed qualitative and transaction-level data to analyse an early and prominent dark web fentanyl-selling operation. The data record the date, drug, quantity, and selling price for 5,589 transactions comprising 872,659 items sold for a little over $2.8 million through AlphaBay. Findings include that the organisation sustained an impressive sales growth rate of approximately 15% per week, com-pounded. Increasing order sizes by a factor of ten reduced the price per pill by approximately 25% for Oxycodone and 50% for Xanax. Those steep quantity discounts imply large price markups when selling further down the distribution chain. Such high growth rates and price markups suggest that it might be difficult to constrain supply by shutting down individual organisations, since any remain-ing organisations may be able to quickly grow to fill unmet demand.

Terrorism is no longer the leading international threat to the United States or its top defense priority, but challenges related to violent extremism remain. The threat from Salafi-jihadist groups such as al Qaeda and the Islamic State has declined, and ethnonationalist threats are largely contained. However, a broader patchwork of violent far-right and far-left extremist ideologies has become more prominent on the global stage. Meanwhile, terrorism continues to overlap in significant ways with strategic competition, especially via Iran's support to terrorist groups like Hamas and Hezbollah.

Numerous studies demonstrate that terrorism causes strong public reactions immediately after the attack, with important implications for democratic institutions and individual well-being. Yet, are these effects short-lived? We answer this question using a quasi-experimental design and data on three successful and three foiled terrorist attacks in the United Kingdom. We find that heightened risk perceptions and emotional reactions in the wake of successful attacks do not dissipate in the very short run but are sustained over time and up to 130 days after the attacks. We also find that, whereas large-scale attacks cause a long-lasting shift in risk assessments and emotions, the corresponding effect of smaller-scale terrorism incidents appears to subside within one month. Interestingly, foiled attacks can also affect public perceptions, which, however, quickly return to normal levels. We argue that the extent of media coverage is partly responsible for the duration of these effects.

This work is concerned with the extent and magnitude of threat related to online radicalization in the context of terrorist acts and related offending. Online influences have been depicted as major drivers for the propagation and adoption of extremist ideologies, which often contain an element of collective grievance, and subsequent acts of violence. This is most pronounced in the discussion of so-called lone actor terrorism, but extends to all forms of extremist offending, and beyond. The present work situates online radicalization leading to terrorist acts within the wider context of grievance-based beliefs and attitudes. Further, it addresses current positions and debates surrounding the relevance and mechanisms of online radicalization in terrorist offending. Recent evidence from quantitative studies is reviewed to estimate prevalence of online radicalization and the level of threat that results from it. This is followed by a discussion of plausible, but opposing, interpretations of the estimates presented. While online radicalization does occur, with and without reference to offline processes, the resulting threat is not overly high. This assessment, however, refers to the present only and is unlikely to hold for the future, given the general growth and acceleration of online activity among terrorist actors

The overarching aim of this doctoral research was to investigate the role of the Internet in radicalisation pathways and offending of convicted extremists in England and Wales. The empirical study was unique because it benefitted from access to closed source risk assessment reports within His Majesty’s Prison and Probation Service (HMPPS). These reports were authored by Psychologists and Probation Officers with access to restricted case documentation and in the majority of cases, direct interviews with the individuals concerned. Findings were based on 235 convicted extremists, all of whom were considered to have radicalised prior to committing their offence. Variables of interest, including offender demographics, offence characteristics and online activities were extracted from risk reports completed from October 2010 to December 2017. Since completion of the doctorate, the analysis has been expanded to 437 convicted extremists, which includes all those subject to risk reports from October 2010 to December 2021. This accounts for close to every convicted extremist in England and Wales considered to have radicalised prior to their conviction.

This report sets out the findings of research to understand the potential of the Good Lives Model (GLM) to interpret trajectories into and out of violent extremism and considers the implications for policy and practice. The Good Lives Model (GLM) is a well-developed manifestation of a strength-based approach to rehabilitation. The model argues that focusing on developing strengths and enhancing protections, rather than solely managing and controlling risk factors, offers a more fruitful route to preventing (re)offending. The GLM has become an increasingly prominent part of efforts to rehabilitate criminal offenders, however its potential with respect to the violent extremist population has not been fully exploited. This report is informed by a review of research on protective factors set out in an earlier report: Conceptualising Protective Factors: Strength-Based Approaches (Marsden and Lee, 2022) that established the theoretical foundation for the empirical research set out here.

This guide sets out the evidence base for ‘online radicalisation’, examining how individual use of the Internet, in conjunction with offline influences, can facilitate radicalisation processes. The UK is the main context of concern, however comparable evidence is found in studies with samples from the USA, Canada, Belgium, Germany, Austria, and Israel. Radicalisation remains a contentious concept and few studies explicitly define ‘online radicalisation’. For the purposes of this guide, ‘radicalisation’ is understood as leading to cognitive outcomes reflected in changes in beliefs and ideas, and/or behavioural outcomes which manifest in changes in behaviour. Two systematic literature reviews (Hassan et al., 2018; Carthy et al., 2020) directed initial searches for relevant research. Further literature was identified through forward and backward citation searching, and narrower key word searches conducted in Google Scholar. Literature searches were completed between June and August 2022. The guide primarily examines literature published between January 2017 and July 2022. Although the evidence base remains modest in size, the research underpinning this guide is assessed to be good quality. There is a growing body of evidence that uses qualitative and quantitative methods to examine a range of factors which are relevant to online radicalisation.

This paper describes the recent history and present status of proscribed organisations under the Terrorism Act 2000 (the “2000 Act”). Prior to the 2000 Act, proscription was exclusively concerned with terrorism connected with the affairs of Northern Ireland. Under the 2000 Act, proscription was extended to include organisations concerned with both domestic and international terrorism. The Home Secretary may proscribe an organisation if they believe it is “concerned in terrorism”. If the Home Secretary believes that an organisation meets this statutory test, they must then decide whether to proscribe the organisation. In doing so, they must take into account various policy considerations. Consequences of proscription The 2000 Act sets out a number of proscription offences. These include belonging to or inviting support for a proscribed organisation; arranging or assisting with the arrangement of a meeting that supports a proscribed organisation; addressing such a meeting; or wearing clothing or displaying articles in public which arouse suspicion of membership or support of a proscribed organisation. It is also possible to impose financial sanctions on proscribed organisations.   Current proscribed organisations As of September 2023 there were 79 international terrorist groups proscribed under the Terrorism Act 2000 and 14 organisations in Northern Ireland proscribed under previous legislation. In November 2021 the Home Secretary announced that the Government had laid an instrument to proscribe Hamas in its entirety, ending the distinction between different wings of the organisation. In September 2023 the Government laid an instrument to proscribe Wagner Group, a private military organisation which has acted as a proxy for the Russian state. The Government considers it to involved in committing acts of terrorism, including in relation to its involvement in Russia’s invasion of Ukraine. The Annex to this paper includes a current list of proscribed organisations and a description of their activities. Criticisms of the proscription regime Proscription has been characterised as a powerful deterrent, a way of tackling lower-level support for terrorism, and a signal of rejection by society. But questions have also been raised as to its utility in combating terrorism and its compatibility with the rule of law. The former Independent Reviewer of Terrorism Legislation (IRTL), Lord David Anderson KC, repeatedly recommended the introduction of time limits for proscription orders, as have his successors, Max Hill QC and the current IPTL, Jonathan Hall KC. However, the Government has so far declined to follow these recommendations and currently deproscription is done by way of application only. As a consequence, groups that no longer meet the statutory requirements for proscription continue to be proscribed, a situation described by Lord Anderson as “an affront to the rule of law”.
