Y'all might be waking up to oodles of propaganda about how emergency whistles are actually bad and traumatizing.
I dealt with answering questions to that stuff a bunch privately and don't really wanna rehash it, but:
If fascist politicians are saying the whistles are weapons of terrorism and need to be banned, and liberal non-profits are saying whistles are also bad and need to be banned...
...maybe you should take carrying an emergency whistle more seriously.
