Stereo when did you qualify as a doctor. Do you know you are not allowed to give a medical opinion without proper medical examination. I would have thought That even you would have realised that the referee had displayed , even for Scottish referees, a remarkable leniency for Celtic's opponents. The only View we have from a Celtic supporter who was at the match was that he was a cheat, so maybe I wasn't so far wrong but you had to become abusive.
Watching controversial incidents, such as potential penalties on TV is a better way to judge whether or not they were actually penalties... First reaction at a game is to obviously believe it was a penalty (knee jerk/crowd reaction), however, after you watch them again (and again) you may change your mind. I saw many incidents at Celtic Park that had me shouting for a penalty/sending off/goal but when I the watched highlights on TV, I often changed my mind.
