How many thousands of prisons will that take and where are you going to find the money to build them?
Tent compounds in the Mojave desert and make them grow their own food.
Make it miserable enough, like 2 years for a 1st offense, and the criminal element would be greatly reduced in a short period of time.
There would always be a few like a cousin of mine that except for my aunt blowing a fortune on lawyers would be doing 25 to life where he belongs.
