They're doing this in the UK right now with security for cultural events.

Since the Manchester Arena terror attack (awful, tragic, evil, and an isolated event), it has been mandatory for music and live theatre venues to have an absolute army of "security" staff checking people's bags.

A full 95 percent of whom would be entirely and totally useless in any actual emergency or danger situation.

It's one of the things contributing to the ever increasing price of show tickets, but basically it's a tax on people who can afford live shows to create jobs for an otherwise fairly unemployable sector of the population (young and not much education - way too little natural demand for that in central London to mop up all the supply).
