Tell the partner to get off his neck because he can’t breathe. Relieve him and tell him that i got it from here, go get the car ready to put the arrestee in. As long as he’s not combative, sit the man up or roll over into the recovery position and make sure he’s conscious and talking. Then put him in the car and wait for ambulance or supervisor to arrive on scene if necessary to avoid the public shit-show with the bystanders.
I’ve responded to many uses of force involving my colleagues. I’ve noticed that often times cooler heads are needed at these incidents and the officer who just got into a fight with someone will likely still have high adrenaline and tunnel vision, and should be removed from the arrestee to cool off.
This sound reasonable.
Would you follow up after the event with a chat or official complain? Genuine question here. Trying to understand the police culture there
