I'm sure Laurinaitis is going to try to snitch his way out but he should pay for his participation too. Let him expose everyone involved then nail him too.
I'd guess he knew Vince had mistresses or w.e but maybe not necessarily the details of whatever was actually happening.
Now if he knew but didn't participate, what does he do outside of voting against Vince returning if at the time the woman is under a NDA and she seemed to be ok with the payout...
