Raven talks about the ineffectiveness of current criminal laws and legislation in preventing crime. He believes that this is partially the result of lack of law enforcement. He discusses the four problems identified by reformers focused on California's criminal justice system: (1) plea bargaining, (2) pretrial delay, (3) the exclusionary rule, and (4) the availability of mental defenses to criminal liability. Raven opposes building more prisons and the government's incapacitation policy; he thinks they cost more money without producing results. He calls for better long term solutions to crime by dealing directly with root causes such as poverty, racism, and drugs. in the future, Raven suggests that crime prevention can be achieved through theories of punishment, rehabilitation, deterrence, and incapacitation.
