I wasn't in the situation, so I don't really know, but what would I (or any of you do) if we were in the situation there in LA? Would you have surrendered your guns? It's the kind of thing that they call us 'conspiracy nuts' for even dreaming about.
I remember well how the confrontation went in N.O. The National guard went house to house, in an area that wasn’t flooded, First they asked for their guns and then they searched the homes just to be sure.
Obviously the home owners were out gunned and over powered.
You should consider this and have something in reserve, very well hidden and be prepared to give up something as well.
Or die on the spot, not a good option.
I'm pretty sure the statute of limitations on the civil suit have run by now, but they could have potentially sued any National Guardsman they came in contact with that took their property (guns) from them. They also could have sued the National Guard generals (or other officers in charge) that ordered the enlisted men to carry out the confiscation.
Maybe they would have been awarded only nominal damages (like $1, plus return of any filing fees, etc.), but at least the government would have been sent a message that what it did to New Orleans residents was not only unconscionable, but, indeed, UNCONSTITUTIONAL.
