IMO as a LEO.
I think the dumbest of politicians knows that total firearm confiscation would be a suicide mission.
I think there would be very few gun owners that would just hand over their guns without a fight, myself included.
Confiscation would have to be done by the military, because I don't know any cops personally that would take part in this, even if it meant their job. I like my guns, and freedom, much better than I like my job.
I think it would ignite a civil war.
I know how polls and statistics can be skewed to show anything you want, but fwiw, I remember a poll of military personnel several years ago, and a huge majority stated they would NOT carry out orders to confiscate weapons from American citizens.
