I'll absolutely accept cocaine overdose if that's what the evidence supports (including an honest time-line), but adding 'excited delirium' to the explanation is "unhelpful" (quoting Braidwood), and is extremely dangerous in the larger picture.
The problem is that if the police are presented with a subject that is acting insane, and they've been appropriately trained about drug overdose symptoms, then perhaps they'll treat it as the medical emergency that it is and not toss the subject into a cell.
But if they're confused by unenlightening talk about 'excited delirium', then suddenly they don't know what to do. Subject gets tossed into a cell and dies.
See previous post [LINK].
Dr. Margaret Thompson, an emergency medicine physician with expertise in cocaine poisoning and excited delirium, told the inquest there was enough cocaine and its metabolites in Marreel’s system to kill him. ... During her 24 years as an emergency room doctor, said Thompson, she has diagnosed cocaine toxicity on an almost daily basis, but has seen excited delirium only once.
She's an expert in 'excited delirium'. She deals with cocaine toxicity on an almost daily basis.
But has only ever seen one case of 'excited delirium' in 24 years.
Talk about "unhelpful", geesh.
Free advice: if you see (or think you see) something bizarre just once in 24 years, file it away in the back of your mind along side that UFO you might have seen. Seriously.
