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!
