If it was some random off the street that had walked on stage and assaulted someone - arrested, still sitting in jail today
If it had been someone that was allowed to be there - seat filler, production assistant, b-movie actor - arrested, in jail
If it had been Kanye, or Mel Gibson or another self important celebrity, they would've at least been escorted out.
WS was allowed to return to his seat, accept an award and be toast of the party.
And he did strike him, not a slap. That was a full extended punch that was followed thru on - palm out first - the way they teach in self defense classes (or on movie sets) and can be more effective than a clinched fist punch.
And go back to the video - CR says "I could.." (say something that would really embarrass you right now and take you down) but he stopped himself and took the high road.
WS should be persona non grata in Hollywood but I'm sure unfortunately he'll be allowed to have his redemption tour.
