Bump-fire in itself is a turd. That's not the hill I'm fighting for. I'm fighting against the idea that banning stuff will solve this. I'm fighting against the idea that it's the tool at fault and not the shooter.
Is THAT hill worth the fight?
Now that I can understand. I don't think anyone else is going to think of it that way in Washington.
Like anything else gun-related, this only hurts the people that don't use them for nefarious reasons. Of course if a killer wants one, they'll get one.
