he guilty should be punished to the full extent of the law.
If the cops set up an OK Corral situation and got a bunch of people killed, do they count as guilty?
I would suggest that if they kept medical help from being administered after the scene effectively was secured and people bled out during that time they are at the very minimum guilty of manslaughter and need to be permanently removed from law enforcement.
If they retired since the incident their pensions need to be rescinded.
What does the video show?
The problem is, who would indict them?
