In my understanding, owning guns for self-defense or sport are only secondary reasons to support the Second Amendment. Though gun advocates often shy away from making the case, the best and most vital purpose of an armed citizenry is to be a buttress against tyrannical government. Now, I’ve never owned a gun, and I have no reason to believe that the time for aiming muskets at government troops is close or inevitable. And if it needs to be pointed out, those who do are nuts. As tragic as events of Ferguson have been, the situation certainly doesn’t call for any armed rebellion.
And yet. When the police block Main Street with tanks and aim their high-powered rifles at unarmed protestors, I don’t think to myself: “Hey, thank goodness those citizens have no way to defend themselves.” Apparently some people do.
