I am not a medical professional but it seems to me that the drug PCP is the primary factor leading to his death.
If Prude had not been on PCP he would not have been acting out.
If he had not been on PCP he would not have been in contact with the police.
If he had not been on PCP he would not have been in a spit hood.
If he had not been on PCP he would not have been restrained.
In all respects, if he had not been on PCP he would not be dead.
Yep - another criminal does the OD death dance and it’s the cops fault because they didn’t have his whole medical profile on-hand....
