Uh... Because it's a TV show? Undertaker and Kane are murderers, Kane himself is a rapist, Vince drugged his own wife, people constantly assault each other out of the ring, and that's only the top of the list. Laws don't really work in WWE land
It may be a TV show, but I always saw Vince putting raw emotion into his voice that I can't help but find convincing.
Let's look at the legal side of this, shall we? How about we consider the charges that could be pressed against him?
Drugging his wife: coersion through substance abuse.
Getting William Regal and Stone Cold to kiss his butt so he can keep their jobs / Shawn Michaels to kiss his butt to let Marty Janetty sign on with the company again: disorderly conduct, extortion, indecent exposure.
Demanding that Paul Heyman brings the Undertaker to the pay per view in progress: arson threat, battery, extortion, terroristic threat, declaration of intent to orchestrate kidnapping of minors and rape of an adult, declaration of intent to commit first degree murder in public.
These are just a few of 'Vinnie Mac's' theoretical crimes for his rap sheet. Would you all care to add to the itinerary or mention charges I am unaware of to improve the ones already listed?
