They don’t want background checks to permit any sales. They want to ban firearms and this week they are saying “These weapons must be banned”.
Well, they can’t ban guns because of the 2A. They can try to ban some guns but they’ll fail and it still won’t prevent a determined mass murderer. It won’t even slow him down. In fact, much like when they tried to end the meth crisis by making us sign for cold medicine, they’ll just make an already bad situation worse because they don’t know crap about guns, bullets, external ballistics, terminal ballistics, etc. They just know politics.
