I simply try to live by the golden rule, do unto other's yada yada yada......so, would the policeman in question like to have some guy putting his knee into his back or neck for more than, say 30 seconds.......no one would.........and you'd be rightfully pissed off and agitated and moving and squirming around to try stop the pain being put on you. Anyone who says otherwise, please volunteer your 7-8 minutes and report back, whilst hand cuffed......
To have a cop say SOP is, subdue, and stop the forceful kneeling after subdued, seemingly is common sense an what should be practiced to de-escalate the situation instead of haranguing a person and continuing to piss him off and make him feel discomfort or pain..while trying to calm him down ......and this is prior to any medical issue real or not......in today's litigious world, really, the second anything medical comes out the red tape starts and you have no option, but, to react and make the suspect's health priority.......this cop is unfortunately "that cop", and once again, makes life for those who do serve the uniform with honor, less honorable by association.
