I don't care if the terrorist was still dangerous or not. The only good terrorist is a dead terrorist. I don't want to pay for his imprisonment, food, trial, etc. I'm very happy to pay for the bullet that went thru his head.
ab-SO-lutely
cost to care for a prisoner for 1 year: $50,000+
cost of 1 m16 bullet: about $0.30
simple math!
