If you're willing to get involved in a police chase over a flipping traffic ticket, you deserve to be classed as a felon.
I would also point out that the murderer in this case was just a complete loser, a useless drunken bum who snapped because his girlfriend left him.
If he had not been a member of these groups, he would have just gone to a church or a mall and done the exact same thing that he did at the gurdwara.
This is not a competent, together individual who would never otherwise have done this except that he became "so twisted by hate" that he made a calculated, ideological decision.
Ideology was not his motivation for his cowardly attack, it was just the determining factor in which target he chose.
“If you had a loved one who was killed by some clown as she was leading the police on a chase, you’d probably think differently.”
Oh, well if that is the logic we are following, then let’s just charge them with a felony when they go to get a driver’s license, since after that, they MIGHT flee the police, and then they MIGHT run someone over in the course of that chase. Nip it in the bud early, I say.
