DCA,
I understand your point. Having not been at the game myself, I can't comment on the call made. I can assure you however, that every referee that I've ever talked to doesn't want to be put in a position that a call he does/doesn't make decides the outcome of a match. I don't know what the referee coded the card that he gave for "pulling the shirt". I haven't heard of that one, it could have been PI or any number of things.
But hardly can a PK in the 2nd minute of the match be considered deciding the outcome of the match.
