Right, you're having math troubles again.
The US population is 3.8% of the world's population.
The fact that we have 14% of the gun deaths?
THAT'S SUPER BAD. If guns made no difference at all, we should have 3.8% of the gun deaths. If guns helped with the situation, they'd be less.
You just proved right there: Guns make our problem more than three and a half times worse!!!!
