Making guns illegal doesn't stop people from possessing them. Over 80% of gun murders already occur with an ILLEGAL gun. I said that. Apparently you missed that part. How convenient.

There is no country that is comparable to the US in terms of size, economic development, crime rate, etc. Every modern country, however, that has a powerful black market, specifically one that supplies drugs and guns has a criminal element that protects that business and another criminal element dedicated to robbing those people.

The handguns you're talking about are already illegal. Again, if you don't understand gun, then keep researching until you do. You're not ready.
