There is no precedent for a points deduction and it is potentially dangerous ground as it opens the possibility of fans staging "tactical" pitch invasions to affect the results of games / abandonments etc.
A lot was made of what went on on Saturday but although all those that entered the field of play are bellends it could have been a lot worse, from what I saw there were some bottles (plastic presumably) thrown and some aggressive gesturing but not much else. Don't know if there was any further confrontation after the game as I went back to the car and went home although the coppers had the helicopter up and what appeared to be half the West Midlands police outside complete with dogs. Both teams in Stoke have poor reputations for crowd behaviour particularly Vale and lord knows we have our fair share of idiots when it comes down to a bit of aggro in town centres but I didn't see anything apart from the local untermenschen hanging around outside the ground.
