I have a Gun Control plan that is guaranteed to lower crime rates and lessen the death toll in mass shooting incidents. (They can not be prevented entirely as crazy people abound. )
1) Every law abiding, non prohibited person must own and CARRY a fire arm at all times. People with religious scruples against violence can substitute a first aid kit for the firearm and replace firearms training with Red Cross Medical training.
2) Make "gun free zones" illegal.
3) Imprison any and all anti 2A activists and politicians for conspiracy to commit murder, rape, and robbery.
