The culture of guns beyond just law

Seems like a lot of the shootings, like the recent school shooting in Texas, happen in areas where there are lots of guns. Gun culture and many guns around. The person who did that shooting used a gun that his father had, so I hear. I'm in favor of changes in gun laws, but that isn't necessarily the magic answer. The law might not make that much difference, but it's up to people to not be so into guns. Have less guns around.
