RT Article T1 Is Gang Violent Crime More Contagious than Non-Gang Violent Crime? JF Journal of quantitative criminology VO 37 IS 4 SP 953 OP 977 A1 Brantingham, P. Jeffrey A2 Yuan, Baichuan A2 Herz, Denise LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/1776231317 AB Objectives Gangs are thought to enhance participation in violence. It is expected then that gang-related violent crimes trigger additional crimes in a contagious manner, above and beyond what is typical for non-gang violent crime. Methods This paper uses a multivariate self-exciting point process model to estimate the extent of contagious spread of violent crime for both gang-related and non-gang aggravated assaults and homicides in recent data from Los Angeles. The degree of contagious cross-triggering between gang-related and non-gang violent crime is also estimated. Results Gang-related violence triggers twice as many offspring events as non-gang violence and there is little or no cross-triggering. Gang-related offspring events are significantly more lethal than non-gang offspring events, but no more lethal than non-contagious background gang crimes. Conclusions Contagious spread of gang-related violent crime is different from contagion in non-gang violence. The results support crime prevention policies that target the disruption of gang retaliations. K1 Violence Prevention K1 Point process K1 Gangs K1 Assault K1 Homicide DO 10.1007/s10940-020-09479-1
