Did you expect them to be?
Yes, they should have been hooked up for Murder in the death of Kathryn Johnston, they were violating the law and a murder ensued from their actions,
If some punk knocks over a liquor store and shoots the owner, when they are caught, they would face the death penalty, there wearing a badge while they broke their own laws is no excuse at all, Mrs. Johnston’s death was a forseeible consequence of their crimes.
