lol! I love it! As sad as it is... Cars have killed WAYYY more people, recently (since they became popular, and without proper education and application). I see the issue with cars as complacence (not paying attention), ignorance (not knowing how to drive, or that you actually have to watch what is going on), and stupidity (texting, drinking, overall distracted driving).
Texting while walking has killed people. Are we going to regulate cell phones?
Like was mentioned earlier (and ties into the OP), things that seem strange, are often normal to others.
We cannot discuss different region's history as an apples to apples comparison, as different socioeconomic classes, government regulations, entitlements, history, and ethics, etc... that all lead to our society's behavior. A gun is simply a tool, just like a cigarette, drumstick, cell phone, car, or that new Sabian AAX Air Splash (that I like so much). Simply because I purchase a cymbal, does not make me a great drummer. But it can enable me to sound like one.
