I just have a really hard time seeing police and then military attacking gun supporters regardless of who is in power. Police and military are overwhelmingly conservative and libertarian.
Sounds like you're saying that conservatives and libertarians have little to fear from the government, regardless of how many guns they have. But if you're not a conservative/libertarian, well, your family might end up in a "detention center"... and the number of guns you have won't prevent that.
Again: if you belong to a politically powerful constituency, you don't need guns to protect you from the gov't, and if you don't, guns won't help. I assure you that had the New Black Panther Party staged a hostile armed takeover of a federal law enforcement building, the feds would have rained ordnance on them and they wouldn't have gotten a month of play-acting first. Same goes for any NBPP member who dared train a rifle on federal law enforcement agents.
