This discussion is an example of how football fans have become conditioned to being criminalised. The media is the same, saying that the pitch invasion is the problem rather than the behaviour of some idiots afterwards.
For me a pitch invasion is not a problem. Bit of fun, and I've had several memorable days on the pitch after big games (Forfar anyone?). Fans come on, wander about and then are directed back off. Bit of tolerance, especially in circumstances like hibs - 114 years since last win, just lost league play-off, lost league cup, last minute winner etc.
Every team has clowns who won't behave once on the pitch - us included.
There are laws in place to address bad behaviour by those on the pitch and plenty of CCTV and coverage to spot who they are. Identify the 1%, prosecute if appropriate, ban if a football issue. Let the 99% enjoy themselves peacefully. And leave fining the clubs out of it. Maybe fine the clubs but only if they don't co-operate in identifying and banning those who attacked rangers players, fought on the pitch or damaged the pitch or goals.
My point is this - 99% weren't involved - leave them alone and let people invade the pitch now and again. Manage the situation appropriately - let them on, then guide them all off again (and they'll go no problem as the hits fans did yesterday). Deal with the morons directly and stop making every football fan a criminal.
As an example, there was a pitch invasion at Connaught yesterday after beating Glasgow - no headlines I've been able to spot there.
