RT Article T1 Depictions of Firearm Violence Perpetrators and Support for Firearm Policies: An Experimental Survey Analysis of Mental Illness and Criminal Background JF Crime & delinquency VO 71 IS 8 SP 2646 OP 2678 A1 Semenza, Daniel C. A2 Berryessa, Colleen M. A2 Sierra-Arévalo, Michael LA English YR 2025 UL https://krimdok.uni-tuebingen.de/Record/1926894049 AB We used an experimental study design with newspaper vignettes to examine how characteristics of gun violence perpetrators including mental illness and previous incarceration influence three categories of firearm policy support in a national sample of U.S. adults (N = 3,387). Depictions of mass shootings elicit greater support for firearm policies than other types such as suicides, accidents, or street-level homicides. Further, depictions of mental illness and previous incarceration increase support for policies regulating who may legally own, purchase, and possess firearms. Demographic characteristics of perpetrators such as gender and race largely do not affect public policy support, although personal characteristics of respondents themselves are predictive of support.
