@Along_the_Wire and anyone else who cares.
This was as recently as 2016. A 32 year-old in Dallas had themselves called 911 asking for help, stating they were worried after having taken a drug and having not having taken their schizophrenia medication.
Police were the first to arrive on the scene. By the time the police had arrived, the man had already been handcuffed by local security guards and posed no threat. Police pinned him to the ground with his nose squashed down for 13 minutes, all the while laughing and joking, e.g. “Is he asleep?” “Wake up, time for school”. He died before the ambulance eventually arrived and took him away, without the officers even taking a pulse.
An autopsy classified his death as a homicide, a victim of sudden cardiac death due to “the toxic effects of cocaine and the stress associated with physical restraint.” It took a 3 year legal battle for the police bodycams to even be released. The city and county had fought to prevent the release of all records related to his death. The policemen remain on active duty.
The victim happened to be white.
