Kill them all! This guy proposes that we execute the family members of suicide bombers (this is argued in the context of Israel-but it seems applicable to the debate going on here now). Seems to me this is a classic is vs. ought problem. I think from an anthropological perspective the solution is very efficient-but from a liberal perspective it is unconscionable. I'll ignore evolutionary psychology on this one-though I might add that some of the fanatics of 9/11 might not have cared had their quasi-infidel families been sent to meet them in hell.
