Well, I'd start with what you suggested in your previous post and add requiring a license to own a gun...And don't let the NRA/NRA-supported pols off the hook so easy, "I do not accept your perception that "strong gun laws" would end gun violence" and nobody suggests stronger gun laws would end all gun violence.
Evidently NRA-supported pols laugh at a large majority of Americans - including gun owners - who favor strong gun control laws.
