He bypassed the Legislature to enact some laws about who needs to do the background check when selling guns. Some people at gun shows, he thinks, might not really be regulated already.
I agree with Game, practically meaningless rules. The Past is not Prologue, every year "perfect" citizens buy guns and pass the background check, and then go do something wrong with them.
If anyone suspects they won't pass the background check they go private somehow, buy them from some drug-running hoodie or something, totally unregulated.
The really needless deaths/injuries are ordinary people who have no evil intent, but don't know how to handle a gun responsibly. Some sorts of laws could educate/raise awareness and stop a lot of deaths.
