Check out what the fed, state, local police forces, in conjunction with the National Guard (strong arm muscle) did in New Orleans, La after Katrina and Greenwood, Ks (??) after a tornado wiped out the town.
Many residents in Greenwood, Ks had perfectly good homes that were untouched by the tornado but they were all forced to leave their homes and town. One resident who refused to leave, armed themselves and only a single state trooper prevented a shootout by convincing the authorities to back off and give the home owners time to think about the consequences of continued resistance.
It's very interesting to review what occurred in town once all of the locals were removed. Check it out!
With respect, perhaps it would be better if you were to post, cite or describe what specifically you are referring to, so that we are all on the same page, and then we can discuss it, if that's OK with you?
Personally, I've found that there are a lot of untrue but persistant rumors and myths in circulation about what actually happened in NOLA particularly, and about who did what, and how much of it really went on.
I'm always on the lookout for credible stories of people being forced into, kept in, or otherwise abused under color of authority in sanctioned disaster shelters. I'm still looking, but I've collected some real horror stories so far, although of the bad conditions and incompetent management kind.
