And if you're training with an unofficial "militia" or something, you're a flaming idiot, and an asshole too. You can use your pistols or rifles to shoot (or scare) home-invaders, fine. You can use them to shoot deer. You can use them to shoot inanimate targets for fun and skill. But if you use them to shoot police officers, or FBI or ATF agents, or U.S. soldiers or National Guardsmen, you will deserve everything you get including death. Don't even think about it. Anyone who thinks the "insurrectionary theory" of the Second Amendment has any relevance or value in this day and age is way worse than stupid.
