Introduce corporal punishment in the form of caning to the US Criminal Justice Sysem. It is widely used in Singapore and contributes to the country’s extremely low crime and recidivism rates. The punishment should be carried out like in Singapore, with a rattan cane on the bare buttocks. It should be used in addition or in lieu of short jail terms and as a disciplinary punishment in prisons. Caning causes no permanent injuries apart from scarring and allows the offender to resume working after one or two weeks.
Corporal Punishment does NOT violate the 8th Amendment because it was used in the USA for centuries. Some states still had it as late as the 1950s. It is not “cruel and unusual” as long as it is carried out under medical supervision.
Caning should be mandatory for all violent and sexual crimes, for vandalism and shoplifting. It can be carried out in private or with select witnesses, like executions.
It is also necessary that all illegal immigrants are given 10 strokes of the cane before being deported, for additional deterrence.
