Backup arrived and the fight broke out immediately after they got there. Regarding more backup, the entire Cottonwood PD at night is 8 men. As soon as 3 and 4 showed up the fight broke out. All 8 responed eventually, the fight went on longer after the cruiser with the cam left with the shot officer but the worst of it was what is on camera I think.

I'm just saying it's easy to second guess everything but you don't expect a family to start throwing punches when asked to separate for questioning. I don't see evidence that they "knowingly got into it", the brawl was taken to them before officers 3 and 4 had time to sort anything out. The fight was boiling as they got there.
