This is one of those issues that people have a myriad of solutions for that they want to share, and I've just learned to appreciate the mental effort as it's usually coming from a genuine place. Too often though it's like, "if we just changed urban zoning laws and new construction requirements and how society operates and the societal expectations of parents, children, and child-rearing, we could really solve this gun problem!"
Sure, but IMO let's get guns out of people's houses and harder to get period.
