YouTuber ReThinkingTourism follows up the honest pre-flight safety demonstration video with the brutally honest airport security announcement. Really more painfully obvious than brutally honest. Sadly, the people who need to see this won't. He mentions a remarkable stat about TSA's security theater:
In 2015, TSA flunked its internal security test badly. That year it failed to detect smuggled weapons and explosives at airport security checkpoints 96% of the time
In case you need a citation for that fact, here you go.
