This may be decades late for some people but in case your idea of caning comes from The Simpson's Boot, what Singapore deals out as legal punishment is far worse than just a spanking.
Four of my relatives lived in Singapore in the 80s and they were warned to beware of anyone who walked with a peculiar gait. Canings can permanently affect the skeletal structure (effectively marking criminals for life).
Rush and some other people who didn't know much about the subject seemed to think that caning would be good for the U.S. Well, maybe they'd be fun to watch but they'd keep many ex-cons from even trying to go legit.
Tarring and feathering tho'--that's an idea just waiting to come back.
