" So now thought is a crime and we are all subject to the laws of Indian tribes?"
I'm gonna be an optimist here - that probably doesn't extend the jurisdiction of the Indian tribes but allows DA to assist them in law enforcement.
And for a legitimate case -like a serial killer, help is totally appropriate.
But what if the Indian Tribe law is unfair - it sounds like the DA may still hve to help.
Are you Daft? Serial killers don't do it out of Hate, and there is no problem prosecuting them, just catching them.
