What we need is to send in some NYC or New Orleans cops to break a few heads.
I got a better idea. Everyone that is on death row in the US on charges of murder be let loose in the streets of these cities. Give them all the ammunition they could possibly need and let them have some fun. If they survive they be granted full-pardons and allowed to reside in the foreign city of their choice.
BTW, wasn't there a movie patterned after this???
