Doctor sees cocaine overdose on a "daily basis", but also admits to having seen what she describes as 'excited delirium' only "ONCE IN 24 YEARS".
Depending on their assigned beat, MOST police are not going to witness cocaine overdose on a daily basis. Some certainly might, but there will be many more doing paperwork or writing traffic tickets that will bring the average way, way down.
So the average police officer (in comparison to the good doctor) would be expected to see a case of 'excited delirium' once every, what?, 120, 240 or perhaps 480 YEARS ?!?!?!!
The average police officer is as likely to see a unicorn given that sort of multiple-century timeframe. It'd be a pony with a horn glued-on by drunk students, but given hundreds of officer-years, someone is going to see what looks like a unicorn.
Given this relative occurence data, from a self-proclaimed expert in the field of 'excited delirium', the following lesson plan is presented for your consideration:
'Excited Delirium' for police - what you need to know1) 'Excited delirium' may not even exist.
2) Even if it does exist, it's so incredibly rare that you're not likely to ever see it during your entire career in law enforcement.
3) If you even think about it, then it'll just confuse you when you should be responding to the underlying drug overdose as a medical emergency.
4) So fugetaboutit! As a concept, it brings extreme negative value. It's dangerous. It's useless. It's unhelpful.
5) Just treat the insane subject on the assumption that they've overdosed on drugs, likely cocaine.
Here endeth the lesson.
PS. 'Excited Delirium' is however a very handy excuse in case you've accidentally tasered someone to death.
