Absolutely. The flimsy "evidence" I've seen so far for the Michigan shooter's parents is they allowed him "access" to a gun and they didn't bring him home on the particular day of the shooting.
That could be just about any school shooting that has ever happened.
So people should either be in favor of all of those parents going to jail or none of them going to jail. It's the shitheads like Seran and I'm sure Keller who only want this standard applied to people they don't like.
