With regard to this part, I’d like to point out that I know various gun owners who don’t have any intention of waiting until “ATF comes to their home in force, with dozens of SWAT officers”. Really, if you’re trying to stage an armed rebellion, laying back and letting your enemies choose the time of your battle is doing it all wrong. Sun Tzu wrote “If he is in superior strength, evade him” and “Attack him where he is unprepared, appear where you are not expected.” That seems like pretty sound advice to me.

Probably various ones, but let’s go with the gun confiscation thing for now.
