Indeed. I read an article quoting Kenny Jacket, I believe, well after the game, in which he said that he thought the Saints contingent in the crowd had persuaded the referee into giving Saints the two penalties. He thought one would have been ok, but to give two was harsh. He did end his comments by saying that he hadn't seen the events since the match. I think if he had looked at the replay, he would have altered his opinion.
The crowd had almost nothing to do with the second seeing as most of us didn't spot it!
