The precedent has been set. When Dallas or some other city goes up they will seize the guns - for the Jackboots safety. Don't fool yourself.
Have you called your congressman and senators? Have you called the NRA if you are a member?
Frankly, I believe that at this moment, it's the grass roots that needs to be informed about gun rights. People on the street need to hear the question: are we inferior to the Swiss? Are the the Swiss so superior that they can be trusted with automatic weapons and grenades, when we cannot? And do we think that the hard core violent criminals won't bypass these nitwitted gun grabs? And while I'm at it, we trust the Iraqis with AK47s, and we don't even trust our own vets with the same weapons at home, let alone US citizens.
