Oh agreed. But right now most of those people in the dome are just scared, hungry, hot, and terrified. I've seen crowds at Disneyworld rush the busses over far less. Lets try and have a little perspective and humanity here.
As for the looters and the thugs, shoot on sight and hang em up as an example of martial law. Part of the problem here is the authorities let it be known that all the rules were off, worst thing you can do in a disaster.
I suggested to a co worker that leaving the body (with brains blown out)of a looter outside each store would probably act as a good deterrent tofurther looting if there is anything left. Also, snipers could be effective.
Prayers up for the good folks & their rescuers.
