Inconceivable any law enforcement officer thinks it’s ok to put knee on neck for 5 minutes. 4 officers and 1 cuffed suspect doesn’t require extraordinary measures.
You really have no clue what it takes to hold someone down who doesn’t want to be held down.
The kneeling may be called for in short duration, but once someone is down and cuffed (and other officers are there to assist) there’s no excuse for continuing to kneel.
