Don't think you quite understand the concept of freedom of speech...
lmao - so according to you it would be a cinema's fault for not arranging a safe and fair environment if someone decided to go into a crowded cinema and start shouting fire?
mmm.... not so sure you understand the concept of the first ammendment.
Do you understand? It would seem not.
Screaming fire in a theatre isn't a form of protected speech. Or screaming "I have a gun and I am going to shoot everyone in here" or "I planted a bomb under everyone's table and you all have 30 seconds before they detonate". Libel or slander aren't protected speech. Incitement is another one.
What he kid did was obnoxious and annoying but to argue it would have resulted in the same kind of panic, riot or chaos as those examples mentioned above is absurd. He should have been fined or warned and that should have been the end of it. Banning the kid from saying bingo is as about as stupid as it gets.
