“…The first, referred to here as the “differential involvement hypothesis,” is that Blacks simply commit more crime and more of the types of crime (e.g., violence) that lead to official criminal justice system processing (Blumstein, 1982, 1993; Wilbanks, 1987), and Blacks also continue to commit crime (especially that of violence) into adulthood when White rates appear to decrease (Elliott, 1994). 2 The second hypothesis, referred to here as the “differential criminal justice system selection hypothesis,” asserts that differential police presence, patrolling, and profiling, combined with discrimination in the courts and correctional systems, leads to more Blacks being arrested, convicted, and incarcerated (Chambliss, 1994, 1995; Hindelang, 1978; Tonry, 1995; Zimring & Hawkins, 1997). It is also the case that this hypothesis is more likely to apply to the sorts of (victimless) crimes in which there is more discretion available to agents of formal social control (e.g., drug use, “public order” crimes, etc.).…”
