So you think bringing back slavery would be a good idea?
No, I say we have probationary periods.
Put them in the hot sweltering heat for a year, see if they learned their lesson and can function in society without looting, mobbing, raping, pillaging, thugging, etc, and if so, fine, they stay of the work farm.
If they go back to the dirty thug animal ways, back to the farm where they belong.
