Nonsense.
You might want to review some of the video taken after katrina. The National guard was going door to door confiscating all guns. Not just in affected areas but in unaffected areas. They did this by kicking in doors, entering with guns in firing position and forcefully taking the guns. The news interviewed on of the soldiers and he stated he would shoot Americans in necessary. If you say it can’t happen, I say it already has. I fear the military will do what they are ordered to, at least initially.
