smurgerburger, I will offer up the Mindplay case as the example you are looking for. The casino industry knew this was cheating. They can read. They knew using this device, altered the outcome by shuffling away the negative counts. That changed the overall odds. AND they were using a device to do so.
Gaming experts were called as witnesses, that explained the math in no uncertain terms. And what did gaming do? Basically said "stop doing that". No criminal charges. No one went to jail. No one lost their license. There was no class action lawsuit (and there could have been from anyone that ever played at a table/casino using this device). Just, hey stop doing that. Imagine a repeat bank robber in front of the judge and the judge says. "hey stop doing that, will ya"? And the bank robber walks free.
there wasn't even a lot of publicity about the case outside of a few gambling forums and publications. So they didn't even suffer the consequences of bad press/reputation that there should have been involved with an intentional cheating case.
