As a member of the first military unit (from another state) to reach New Orleans after Katrina, I can say without hesitation that WE did not seize any weapons from residents. We had HEARD that the NOPD was confiscating weapons, but never saw it. I know that it was going on, but we were too busy saving lives to do that. All of this is bringing memories back of a survey that was given to some USMC troops in the early 90's, by a officer working on his masters thesis (please take the time): COMBAT ARMS SURVEY: 29 Palms Survey
