RT Article T1 Prison and Violent Political Extremism in the United States JF Journal of quantitative criminology VO 36 IS 3 SP 473 OP 498 A1 LaFree, Gary 1951- A1 Porter, Lauren C. A1 Jiang, Bo 1982- LA English YR 2020 UL https://krimdok.uni-tuebingen.de/Record/173842071X AB In the current study we consider the link between imprisonment and post-prison participation in violent political extremism. We examine three research questions: (1) whether spending time in prison increases the post-release risk of engaging in violent acts; (2) whether political extremists who were radicalized in prison are more likely to commit violent acts than political extremists radicalized elsewhere; and (3) whether individuals who were in prison and radicalized there were more likely to engage in post-prison violent extremism compared to individuals who were in prison and did not radicalize there.
