The rehabilitation of criminals once in the prison system.
Investigative Psychology (although really a seperate science now), which specialises in the finding and subsequent arrest of criminals. There are, to my knowledge, only 3 courses in the world that teach MSc Investigative Psychology (IP). One is at Quantico, taught by the FBI to its agents, another based at Liverpool Univeristy, England, taught by the "founder" of the science, Prof. David Canter, and the last is a MA degree with a concentration in Criminal Investigative Psychology from Vermont College.
