You're not the sender in this scenario, you're the receiver.
Noting that the sender is being weird during what appears to be an emergency is a choice that some people do make, but as per my other list of examples, people in actual emergency situations do sometimes act weird, and dismissing the sender or delaying response on the basis the sender is being weird, has led to actual deaths: https://news.ycombinator.com/item?id=49098781
(The converse: "people can act weird in emergencies" is exploited by scammers so cover suspicious phone numbers and mediocre deepfakes of voices).
I think having my AI raise to me for intervention when it receives an email like the one you described is pretty reasonable, all things considered then.
edit: How would a human receiver know that they weren't being deceived or scammed? In what world would we expect this kind of email directly lead to calling emergency services?
