I'm gonna go on record on this one, and tell you what's going to come of this: nothing. nada. zip. Not one damned thing. Know why? Because it's no different from any other night in the Vieux Carré. I've seen NOPD come into the police station, all bloodied up, carrying in ne'er-do-wells, looking a far sight better than the bad-asses they were bringing in. Sucks to be the bad guy there.
That's the way it is in New Orleans. Behave, or pay the price. Don't like it? Party elsewhere.
