I don't see the problem.
Just because Jails are overcrowded doesn't mean we should stop putting criminals there.
I do agree that we don't want to have to be paying for inmates to sit there, but that's also why I believe they should be put to work for no pay, bring back the good old chain gangs, picking up garbage on the side of the highways etc. Hard labour. Jail shouldn't be a fuc*ing picnic.
