We can't just accept that people are going to do bad, crazy things. We have to come up with laws.

I would recommend bringing God back into our culture, but of course that doesn't play well. You know, we all used to drive around with gun racks and enough fire power to wipe out a neighborhood, but we didn't do it.
Father Knows Best was on TV, and the news was mostly weather. Sure, someone would shoot a President once in a century, but we weren't all out at the Dairy Queen and Piggly Wiggly hammering each other with buckshot.
And we went to church I seem to recall.
