The threat of a mild punishment imposed reliably and immediately has a much greater deterrent effect than the threat of a severe punishment that is delayed and uncertain. A state trial judge in Hawaii, was frustrated with the cases on his docket. Nearly half of the people appearing before him were convicted offenders with drug problems who had been sentenced to probation rather than prison and then repeatedly violated the terms of that probation by missing appointments or testing positive for drugs.

Criminal-justice researchers say it's difficult to quantify how often perjury is being committed. According to a 1992 survey, prosecutors, defense attorneys and judges in Chicago said they thought that, on average, perjury by police occurs 20% of the time in which defendants claim evidence was illegally seized. "It is an open secret long shared by prosecutors, defense lawyers and judges that perjury is widespread among law enforcement officers," though it's difficult to detect in specific cases, said Alex Kozinski, a federal appeals-court judge, in the 1990s.
