In exploring this with you, we did find common ground. There were an unmanageable number of officers involved. That is going to come up in the incident review. I still don't know what I would do if I were the one person calling all the enforcement shots in this scenario. I do know this. No matter what plan I enacted there's be an internet full of people criticizing me. I also know that no plan would guarantee no collateral loss of life.
The "unmanageable number of officers involved" is key.
But even if that had not been allowed to happen and a single qualified incident commander was running the show with a manageable number of officers there was not enough time when that light changed to red and everyone piled up on each other to have changed the course of events....
Unless a allowable distance to follow had been established.
A distance that the bad guys felt no need to protect themselves from.
A distance where they no longer felt the need to fire upon their pursuers.
The chase lasted 20 to 30 minutes, there was plenty of time to figure that out.
Establishing that single thing could have changed the outcome of this event drastically.
