OK, let's see some common-sense, reasonable rules for gun control come from the other side, such as :
Concealed-carry permits be valid across all state lines, in order to prevent crimes on interstate travelers.
A NICS check be performed on all private sales at gun shows, or by a local sheriff on request. No FFL is needed for private transfers.
Require locked storage in a cabinet or safe of all unloaded firearms in the home. Your self- or home-defense piece is exempt.
That's all the gun control I've give you. Now, let's see some common-sense, reasonable proposals for dealing with the mentally ill, criminals, and those on psychoactive drugs, in order to prevent mass shootings.
