Opioids like fentanyl cause tiny pupils (miosis).
George Floyd was an accident waiting to happen. The timing and the venue is what makes this drama so noteworthy.
You are right but the defense attorney seemed to think the pupils were a helpful fact. Perhaps it helps the cop to defend why Chauvin was not given Narcan? Maybe the EMT was wrong? I’m just a lay person so my opinions don’t much matter, other than the jury is made up of folks like me.
