That's fairly precise. The Gun Control Act of 1968 broadly changed the way commerce and ownership of firearms takes place in the U.S.
Some say it's modeled on Hitler's gun control act of 1938-fact is, we had our own gun control act in 1938, that effectively took away machine guns and sawed-off shotguns from the general populace...
If they ever figure out a way to take the guns away (God forbid!) we (humanity) would just go back to killing each other with swords and spears again. You can't stop the violence only prepare.
