Well, if you take away all guns there would be no gun violence.
The rational adult response would be to attack both issues....criminal behavior and the flood of guns.
But left wing extremists don't want to go after criminals and right wing extremists don't want to go after guns.
If you stop criminals from being able to own or possess guns, you are in fact reducing the need for guns.
Reduce the demand, the supply is adjusted.
Problem solved...let's move on.
