The simple reason gun sales increase with Obama is the very reason for the Second Amendment. Citizen protecting themselves from a tyrannical government. Was this true, didn't matter, this is how they felt. This with many on the left doesn't compute. The NFL player are protesting police violence toward blacks, this isn't true that the police are targeting black, but that's what the players have been told. Aren't the police authority, and would the police be among the first if, as many on the left believe Trump wants his way or the highway. And what protects those of you who do not want to comply? So citizen give up there guns, and only the authority and the criminals have guns, then what.
