Is it actually legal then? I know you can get into big trouble if you are caught counting cards in a casino, but it's not against the law right? So I guess then it's just the casino's that don't want you to do it cos they get fleeced?

Surely if it's not illegal then they can't STOP you doing it? Can they "bar" you from a casino if you are suspected/found to be counting cards?

Only ask as I watched "21" last night (good film, but long!) and it made me wonder.....
