As I said earlier, if you catch a terrorist, you tie them to the back of a HumV, and drag them. Too barbaric? The middle East still believes in public hanging. No trial, no jury. You get caught plating a bomb. Hell, you get caught helping an insurgent fix a flat tire, the country will cheer you to the gallows.
