Perhaps it was police attempting alone a situation that really ought to have had medical supervision.
Too bad it wasn't until the coroner's report came out that they found out about the types of drugs he was on. Look how many times people are locked up because they are drunk, and end up either choking on their own vomit, or hanging themselves. Before I went into Corrections, I worked as a Safety Officer in a NY State mental hygiene facility. That was back in 1980. Back then we used to get drunks sent to us by the hospital. They'd end up in the emergency room, be examined by a doctor, then ordered into alcohol & rehabilitation at the psych center. They used to fight us tooth and nail once they found out they were going to the nut house saying: I'm not crazy...I'm just drunk.
