The best thing I can see out of this whole mess is how many people will be forced off their heroin/crack cocaine habit. Being in a area wihtout nothing coming in except food/water has to really dwindle the available drugs on the street.
I imagine that junkies going through withdrawal are responsible for not a small amount of this savagery. Whatever the cause, it is just sickening. People, and I use the term loosely, shooting at the people who are trying to help them. How much lower can things go?
The only drawback at this point to shooting these sub-human pieces of filth is that it will result in more decomposing and disease-spreading corpses in the floodwaters of N.O. Perhaps at this point the folks in charge need to make that tradeoff.
