"Question for you guys on the inside (Gene, in particular) -- to your knowledge, has anyone ever been charged with and
prosecuted for theft for taking roulettes from a Las Vegas casino? Not just thrown out. And not prosecuted for trespass or
some other alternate charge. If so, what result?"

I have never heard of any. I doubt they would ever be charged with theft. The charge would be cheating. Much easier to prove. You took a 50¢ chip. Only possible reason would be to run it back in at $1 or more!!!!
