You already know.....limit capacities....background checks on all purchases....severly punish offenders.....that would be a good start.
Why limit capacities?
Am I not entitled to use whatever means necessary to defend my and my families life?
The gang bangers coming through my front door will not be limited in their capacity to inflict harm. Consequently, my silenced short barrel AR of choice will have a 30, 45, or even 60 round magazine (I possess all legally) loaded or at hand when and if needed. It will have "military" like features that may include lights, lasers, and red dots to better identify my intended target. failing that, I might just ask Alexa to deploy the Claymore Roomba. (OK, that part is just a little humor).
As to background checks. There are already BGC required on EVERY retail sale, yes including INTERNET sales, and most state's require BGC at gun shows (the so called loophole) and many also on private sales. While many states that require private sale BGC have a carve out for immediate family, why should I be required to do a BGC on my close friend of 30 years? Or someone I know and trust that holds a valid state issued CHP/CCW permit? How about an LE I want to sell a gun to? Should LE be exempt? If LE are exempt, why not an honorably discharged vet that holds a valid CHP from multiple states? BGC laws are flawed and only followed by law abiding citizens. THE CROOKS DON"T FOLLOW OUR LAWS.
2A supporters have already given too much with nothing in return.
First was the NFA 1934, a defacto ban on machineguns, short barrel rifles and shotguns, and silencers
Then the FFA of 1938 , enacting FFL requirements
1968 GCA further expanding to destructive devices
1986 the machine gun registry was closed to further registrations, another defacto ban on machine guns by fiat.
1993 BGC laws
1994 assault weapons ban - WHICH DID NOTHING to reduce gun deaths
countless state and local restrictions on magazine size, rifle features and carry restrictions.
These were all rights taken from citizens, never was there any "compromise" or "Common sense" applied.
Any death is tragic. To punish the law abiding citizen for the acts of crazy and evil lawless individuals is punitive beyond comprehension.
ENFORCE THE CURRENT LAWS
IDENTIFY THE MENTALLY ILL AND TAKE ACTION
