No one gun control law will have much, if any, effect on gun violence BUT [View all]

a series of interrelated regulations passed at the same time could make a serious change in gun violence.

Universal background checks are a no-brainer but for them to work there must be a universal electronic searchable data base of guns or it can't be enforced. California has such a system and felony convictions are checked against it so guns can be confiscated when needed.

Permit to purchase to be issued by the Chief Local Law Enforcement Officer with local background checks as well as the NICS. The locals know who the trouble makers are, who has anger management issues and who rack up a number of public intoxication charges and the like.

Background checks to buy ammunition. Can't use that illegal gun if you don't have bullets.

These four items, all passed at the same time can make a difference.
