The effect of the 1977 Canadian firearm legislation on robberies involving firearms is evaluated between 1974 and 1992 using a pooled cross-section, time series model. The results show that the 1977 legislation did not reduce robbery involving firearms, nor did it have a significant effect on the total robbery or armed robbery rates. The legislation may even have acted perversely in that it may have increased robberies with firearms. In general, these results are consistent with previous published findings but contrast with unpublished governmental studies. The implication that this legislation may have acted perversely is new and requires further investigation.

A growing body of literature has explored the ‘life course’ of crime guns, with a particular focus on the time between the initial point of sale of firearms and their eventual recovery by police following a crime. We contend that this examination is incomplete, with limited consideration given to the period between a firearm's first known use in a criminal offense and its recovery by police—which we refer to as time in crime. Increased understanding of this time frame is important given that crime guns are frequently recirculated among criminally involved groups and the recent finding that time in circulation following first known use in a crime is a significant predictor of multiple uses of crime guns. We add to the literature through the application of negative binomial regression to a sample of 310 crime guns used in offenses in a city in the Southeastern United States to examine how neighborhood context and initial incident characteristics influence the number of days that firearms remain in circulation after their first known use in a crime. We found that increased levels of concentrated disadvantage and gang involvement during the original incident correspond with significant increases in time in crime, while increased levels of residential stability and the ability of police to identify suspects are linked with more rapid recovery of crime guns. Notably, these findings hold even after the inclusion of popular time-to-crime covariates, including firearm quality, caliber, and status as a stolen gun.

This investigation exposes gender-based violence in Tibú, a Colombian town located on the border with Venezuela that serves as a drug trafficking corridor for several illegal armed groups. In 2021, at least 13 women were killed and dozens more were forced to flee the municipality amid one of the worst waves of violence ever seen in the area.
