In this case though it actually looks like he was given an overdose when considering his body weight, and he suffered the cardiac arrest enroute to the hospital, not on site. Coroner suggests drug reaction, the hold or asthma attack might have all played a role in the death. Also the recorded audio sounds like he was pleading with the officers and compliant, not that he needed further restraint or sedation.
