Fact. Once 2013 rolled around and Nestor and Kane walked, Rob would have known that criminal liability was not an issue.

Civil liability is only four years, maybe even only three, in Nevada as far as the casinos suing him to recover whatever he won. Assuming they could win on such a claim, Phil Ivey style.

There is no SOL on civil fraud for tax evasion, if the amount in question is large enough, if deliberate and done with specific intent to defraud.

Given that Rob is now talk talk talking about all this, he's not worried about tax evasion, so strike that. So...given that the civil liability was at most four years (more likely just three) for the casinos' suing him, why did he wait until now? why not disclose three or four years after he did whatever he did? And if some clever lawyer could argue that the SOL was three or four years from when they became aware of the fraud, then why would Rob ever disclose?

At the end of the day, at best, it's a headache not worth too much effort trying to figure out when the perpetrator has not given us enough information to assess the situation completely. At worst, it's all nonsense and not worthy of any serious consideration and good only for a laugh.
