What happened in London David?

What can they do if the suspect you are taking them? Can they search or detain you?
They got a little crazy with me in the Binions 3 years ago and I left in a hurry. Once I cashed out on my color the dealer asked if I had more and then if I was sure a few times and then the suit came over but I was paid and left I a hurry. They were only .50 cents roulettes but what can a LV casino really do if they catch you taking them?

Anyone know?

Curious.
