There was 0 protocol with the police Stahl. The police department knowing that there was going to be a chase with armend killers they could have done road blocks before they reached at a busy intersection. It clearly shows on helicopter video exactly what had happened, and were was the swat team. It could had been handled differently if there was an experienced law enforcement agency. On video shows crystal clear that there was no strategic planning just plain ambush trigger happy gun fight. My condolences to the ups family and the innocent people that were there. It was a chaotic scene.
