New Orleans Officials Shredding the Constitution

To my surprise many people are not aware of the unconstitutional seizure of legally owned firearms in New Orleans after Hurricaine Katrina. Not only did the New Orleans Chief of Police and Mayor order the confiscations of hundreds of legally owned guns, they initially denied any takings and it took a federal court injunction on behalf of the gun owners for the City to admit they had possesion of numerous guns. In the first video below you see a New Orleans police officer brutally slamming a 61 year old woman into a wall because she simply possessed a gun to defend her against the out of control looters and criminals that had overrun New Orleans. The next video shows additional illegal confiscations. Not only was the 2nd Amendment clearly dismantled but the 4th Amendment seemed to be clearly disregarded as well. Once the natural right of self defense is taken away by the government, is there any realistic way to believe that an individual continues to live in a free society?
