He was clearly inebriated or drugged.....also combative....I have no issues with constraining such an individual. How that was done is within the law.....the duration could be an issue as has been in the past.
While he said he couldn't breathe, and while bystanders are calling out that they're killing him, telling him that neck holds are physically dangerous, and begging Mr. Kneecap to get up and take his pulse.
Also for 2 1/2 minutes AFTER his bowels and bladder let go.
Two other policemen already had his legs.
He was already cuffed and on the ground on his stomach.
How hard would it have been to just sit on one of his shoulders? No airway or carotid artery issues there.
