i like your way of thinkingAnd once again, the Bible shows us the way to go here. Let me explain:
Gang members frequently have identifying marks. Tattoos, that sort of thing, right? Now, if we take David (God was a big fan of his, you may recall) as an example, all we need to do is organize these guys into units, and send them out into the most dangerous places in Iraq on foot. It's a win win. Either they do the job and take care of our little insurgency problem, or they die, like Uriah did. If King David can do it for some nookie, we should be able to do it to help the gang problem out, right?
