Today in Nagasaki, Japan, the mayor was shot and killed. Guns are outlawed in Japan. The shooter was a member of the crime underworld, had access to guns and did not care for or obey the current laws.
When guns are outlawed, only the criminals will have access to them.
Does this have any meaning or application for the US?
Yeah, laws don’t prevent crime. Criminals don’t care if something is illegal, they’re going to do it anyway. If they didn’t, they wouldn’t be criminals.
So the black market will thrive and civilians will get slaughtered.
