Yeah my point is, there are a whole lot of other things people tend to have in their carry-ons that are critical for their health. CPAP machines, CGMs, knee braces, allergy-specific emergency food, adult diapers, insulin, epi pens, the list goes on.
If there is actually an imminent threat to life, such as a fire, of course all of these things should be left behind. But I'm of the opinion that in no event should anyone's health be compromised in the name of a blanket policy to collect "evidence".
In short:
save lives >> protect health >> collect evidence
