Put some of these one-man crime waves in jail for 20 years, and you’d see a change in the situation.
Oh, wait. Prison in the U.S. is better than the crap-hole countries these people come from. Oh, well.
And pay $15,000-$30,000 year per inmate, which solves to $300,000 to $600,000? No way. Better to deport and only have to bear the transport costs.
Deportation, not imprisonment, is the most cost effective way to deal with illegal immigrants who have not committed OTHER crimes.
