there was certainly a bit of both. I hate any fans who go onto the pitch, they have no right to be there.
The reaction of a few of the wednesday fans was pathetic. No space for that in football, and no excuse for that
Having said that, the palace fans should have known better than to invade the pitch away from home when the opposition had been sent down and the police/stewards should have seen it all coming when it became likely that palace would win - no one should have been able to get past them. The fact that it happened again at Luton the next day shows that it is not a problem isolated to any particular club, but is due to the fact that anytime you get 20/30/40000 people in one place there will always be plenty of pricks. The police need to be more prepared and organised in order to stop this BS.
I was also pissed off with the wednesday fans who invaded the pitch in order to dance around and boot balls into the net - WTF was that about? If they don't care they shouldn't be there and especially shouldn't be anywhere near the pitch.
Wednesday til I die - so so gutted.
