Unable is the wrong word. Unwilling comes to mind. There was a MANDATORY evacuation ordered days before Katrina hit. Yet many able-bodied chose to stay. Now they're living in squalor, in a post-disaster, lawless area, and they are still choosing to stay (shooting at their own rescuers coming to offer aid via boats and helicopters).
Sure, we should save those who want to be saved, but we've also got to accept that some people WANT to be there.
I could see someone taking a pair of Nikes if they had no shoes, or some food or water, but that's about it. Also, have they said anything about gators or mocasins being in the City??? I've heard newscaster twits saying there are critters in the water, but are there any sigtings??? If there are "dead people" and "pets" floating in the water I suspect gators won't pass up an easy meal, and once they know they've found a place with an ample food source to loot... Well, they're oportunists too.
I'm certainly not condoning the greedy looting or lawlessness that's going on down there. No excuse for that. On the other hand, I could understand people being disoriented and confused and scared, given the drastic way their city has been impacted. Many of the people don't want to leave family behind either. That place is a real mess. Having gone through the 94 quake in a place where 25% of the population had to move out I can understand some of what's happening. The first thing I heard when I went outside at just after 4:31 a.m. after being woken out of a sound sleep was a loud rushing noise that sounded like water. Probably a water heater fell over I thought, but was wrong. A block wall had fallen over and ruptured a medium pressure gas line going to an apartment bldg. A few minutes earlier, just after the shaking stopped, the first thought that popped into my head was "Some people just died." Yeah, and more were soon to follow, the closest about three blocks. The first thing I saw when the sun came up was the smoke from the fires on Ventura Blvd. The gas was still gushing, and contunued to gush for 7 1/2 hours.
I talked with a guy from the gas company the next day about how to fix such a gas leak, and asked him for some DC plugs. He got kind of snotty and told me I shouldn't be messing with gas company property. I informed him in no uncertain terms that the next time his company so irresponsibly let their gas escape for "hours" they should come fully prepared to take a bench vise off their line that would be used to pinch it shut. I still have the DC (tapered damage control) plugs, but hope I never need them.
