The number of privately owned firearms has doubled in the US over the last generation even as violent crime rates and murder rates were cut in half.
Most of the murders with guns are inner city minority drug gangs using illegally obtained pistols. Legal gun owners in the US have a murder rate equivalent to that of Japan - ie very low. Since gun laws would only affect law abiding people and as has already been demonstrated, criminals don’t respect laws - including gun control laws - more of the same is not going to reduce crime rates. Indeed all the evidence is that would just increase crime.
Shhhhhhhh! Don’t let the facts get in the way. ;-)
