Ok, so what happens the first time they come to the door and the home owner resists giving up a weapon. Do they beat the shit out of him and cart him off to jail, shoot him or back down?
I have heard they will lose one swat officer for each home invasion. The town in question has about 70-75 cops. There are about 35K residents. If only one percent own the guns in question, that's 350 of them (or us, as the case may or may not be), they're going to need 350 cops. Oh well, they lose.
