Killing what ?Guns and cars, guns and cars. They're either too dense to know that the primary purpose of a car is transportation and the primary purpose of a gun is killing, or they do know, but think that this false analogy is "winning."
But I'm OK with it. Let's regulate guns like we regulate cars. You have to be trained and licensed to use one. It has to be registered with the government and marked with a license tag. It has to be inoperable until you insert a key and turn it on (or these days, have the fob on you and hit the "start" button). You have to pay to have the government inspect it every year or two for safety.
And even a cheap one costs at least $20,000 new.
