Agree with others, that giving the penalty, and brandishing the red acrd are two separate (connected) decisions. He had to blow for the pen if he felt it was, as he was required to stop play (the ball hadn't gone out). You'd think, unless he was 100% certain, that he would talk to his better placed assistant before showing the card. And if he WAS 100% certain, why change his mind at all.
The bottom line of course, is that the correct decision WAS made, but I disagree that the ref's actions were spot on.
