If the votes can be found in the future, a new ban will probably be much worse. I'm guessing that we'd have confiscations. In that case, there will be people who will willingly turn over their firearms to a government they fear. There will be others who will hide them and deny ownership.
Then there will be some who will stand up for their beliefs and refuse at all costs to surrender them. Those are the people that the ATF is worried about. They don't know where they are or how they will find them. They are sure of one thing, when they find them, people will die. Either the gun owner, the agents sent to confiscate the guns, or everybody. There are people in this country willing to stand against a government gone mad. They have a rabid hatred for the ATF and the government in general.
I believe there will be one other group. That will be the gun owners who decide at the time the agents arrive, that they have been pushed far enough. They will decide that they will not allow entry into their home. They will make a stand, surprising even themselves. They will stake everything they own and all they hold dear on an ideal. They will refuse and resist. Live or die, they will be an inspiration to all.
