Youth with access to illicit handguns have an enhanced proclivity to engage in armed criminal violence and self-harm. While theft has been identified as a pathway for youth to gain access to handguns, little is known about whether and to what extent stolen guns represent a viable channel toward putting youth and others at risk. To evaluate this, several data sources and methods are used to evaluate whether handgun thefts occurring within proximity to a school predict self-reported ease of handgun acquisition among young people. Multilevel results fail to show any relationship between the availability of stolen handguns, measured in three different ways, and middle and high school youths' self-reported access to handguns. Microlevel characteristics are predictive of gun access among youth. [ABSTRACT FROM AUTHOR]

Criminal violence frequently increases within jurisdictions following the implementation of self-defense laws. One explanation for this finding is a firearm amplification effect, whereby criminal offenders increasingly use firearms as a direct response to the amplified threat engendered by citizens. Using longitudinal data drawn from the National Incident-Based Reporting System for 95 cities situated in 15 states, we investigate whether the passing of a stand your ground or castle doctrine law amplifies the likelihood of gun use by criminal offenders. Results from a panel analysis show a marked rise in gun use among criminal offenders following the imposition of both types of self-defense laws. These findings furnish empirical support for the firearm amplification thesis. [ABSTRACT FROM AUTHOR]

Although temperature aggression theory maintains that a high temperature engenders more aggressive behavior by irritating individuals, routine activity theory asserts that violent crime increases as temperature rises because of enhanced interaction among the public in outdoor settings. We investigate the effect of maximum daily temperature on whether crime victims are physically injured during the commission of an outdoor criminal offense in Cleveland, Ohio. We focus on violent crimes occurring outdoors because most U.S. households have central air-conditioning or room air conditioners. Two autoregressive integrative moving average (ARIMA) analyses provide support for routine activity theory because although maximum daily temperature has a strong positive effect on the frequency of violent crimes occurring outdoors, it has little influence on the physical injury of crime victims.

Self-help theory posits that a negative perception of police engenders firearm violence rather than simply amplifying individuals' ownership of firearms for self-defense. A racially diverse police force may help decrease firearm use among Black citizens because marginalized groups in society often view a governmental institution as legitimate and impartial when the racial composition of the institution mirrors the population it represents. Analyses using multilevel data show that as the racial diversity of a city's police department increases, Black criminal offenders are much less likely to use a firearm in an aggravated assault and in a violent crime. These findings buttress the claim that the institutional legitimacy of a police agency can be enhanced by descriptive racial representation. [ABSTRACT FROM AUTHOR]
