Because in the event that we are paranoid, he could've been a real cop, and you we would have voted whether we had investigation powers or not. The only "case" against The Rock was that he hinted at being a cop. If we could have voted twice, he would have been our number two. Also, it's:

Night 1: Hogan
Night 2: Flair
Night 3: The Rock
Night 4: The Warrior
Night 5: Bret Hart

And it makes perfect sense if we're a cop and you and Hart are mafia dudes.
