The Illinois State Supreme Court found a strict assault weapons ban passed after the Highland Park shooting to be constitutional in a ruling issued Friday.
Honestly? They'd want to kill the murderer. For people with principled pro-gun stances the answer to the "how many x have to get shot" is all of them. All of x have to get shot. Because the argument is about a right to self defense and very few rights come without potential downsides or externalities of some sort.
Comparing firearms to cars is a bad argument because cars are designed for transportation and guns are designed to kill. America tests and licenses drivers because driving is a privilege. Bearing arms is a right. Comparing guns to cars weakens your argument and makes all firearms owners (myself included) look bad because they are very different things.
I get where you're coming from. Traffic accidents and gun violence both cause death but comparing them does not help our cause.
