its not rocket science, controlling guns has worked in every country that has applied it with zero negative effects... whats the reason Americans don't want to do this exactly?
Zero negative effects for the criminals.
I prefer non-criminals to have the protection they need. Exactly.
Beyond that, I prefer there being the same kinds of barriers to tyranny which got us our 2nd amendment in the first place. The basic concept is timeless and probably as relevant to the U.S. now as it has ever been in this time of weaponized migration, starving local law enforcement for funds and organizationally shackling them, and funding and radicalization of homegrown terrorist organizations such as Black Lives Matter.
Where do you live that you are worried about criminals, how do you live your life that you need to worry about this, please explain.
