Underneath the spreading chestnut tree

Two people are walking through a metal detector on the London Underground. One comments to the other that it’s “a piece of shit that wouldn’t stop anyone”. Result: they are stopped by police, searched, and charged with an offense under Section 5 of the Public Order Act, which prohibits “Using threatening words or behaviour likely to cause alarm, harassment or distress”. In other words: pointing out stupid ineffective security might distress the sheep, so pass a law and fine anyone who does it.
