Criminals do not obey the law. They do not obey the present laws, and won’t obey and new laws.
That tells you that the purpose of more gun laws is ultimately to disarm the American public that is LAW ABIDING. Those are the people that the evil DemoRats fear. And that ultimately was the whole purpose of the Second Amendment. To permit the citizenry to protect itself against a corrupt and oppressive government -— not mentally sick nutjobs.
I've asked the "more gun laws" liberals "Is it reasonable to say the perp is one who makes his living by breaking laws?" When they say "yes", I ask, "Then why do you think passing another law will deter him?". At first there's a deer-in-headlights reaction, and when they can't think of anything else, they say "Oh you damn conservatives just want to kill people." and stomp off.
They're going to be awfully surprised when that doesn't happen.
