I think Canada had 7 gun murders last year, yet they get the same movies, TV shows and video games we get. The biggest difference is the availability of guns here. Right now, there are no laws to prevent that, which is kinda scary. Cops hate armor-piercing bullets, which is understandable since they often wear armor to charge a crack house or whatever. That's one reason Waco burned - the firemen knew Koresh has bullets that could pierce their trucks.
Guns laws vary from state to state, which is crazy.
I didn't know, so I took my Glock to NY and Boston. Ask him if he ever heard of someone being accidentally killed while cleaning a knife. In closing, I don't know your gun views, but to win, you shouldn't be absolutist the other way.
