As for all the "stuff" happening in New Orleans and elsewhere where Katrina struck...
I'm always appalled at how these horrific events can bring out the worst in people. The looting, the shootings, the rapes, etc. Yes, desperate times may call for desperate measures, but sometimes people end up hurting themselves in the long run.
One of my brothers is in the Coast Guard. He's currently working at CG Headquarters in DC. When Katrina started to move towards the Gulf Coast, his office went into overdrive. They were moving ships, redeploying other vessels, checking on their own bases in the Gulf Coast, etc. They were even handling some of the phone calls and pledges during the Concert on NBC last weekend. Well...
There is a Coast Guard command center in New Orleans. It's actually one of their newer places. Well, it was one of their newer places. The day after the storm, a group of people ransacked the place. They took anything and everything that was not nailed down or under lock and key. Thankfully, the guns and ammunition were under lock and key, and were not stolen. Additionally, they destroyed all the radio and computer equipment - some of which was still functional. And to top it all off, they rubbed feces all over the walls. So...
Now the Coast Guard is scrambling to put together some sort of ad hoc outpost since their center was destroyed. Destroyed by the very people who they were/are trying to help. Why destroy one of the few places that could have gotten communications out to those who could help?
Yes, I do think the US government should have come in immediately to help the victims of the storm, but I'm also disgusted by the actions of those few who have hindered the progress due to their own callousness and selfish attitudes.
