From speaking to Jimmy Falconer yesterday I believe this to be correct and ICT are bracing themselves for a fine. More pitch invasions this Saturday and the powers that be are likely to be throwing the book at them. So don't do it.
Police and stewards in Inverness are likely to be more prepared than their counterparts in Ayr were. If fans do come onto the pitch they will probably grab some of them who could easily find themselves ejected from the stadium (at best) and possibly banned from returning. Even if they don't get a hold of you straight away, there will be photos galore of the offenders all over the web and the club might act later.
Maybe you think I'm scare-mongering but this advice comes from years working with the Supporters Trust and seeing the difficulties fans get into when they either break the law of the land or the rules that apply to football stadia. In some cases, they have been put through absolute hell. Don't let it happen to you on what should be such a great day.
So an organised 'pitch invasion' then??
I think everyone realisies the militance of the stewards at TCS so no one will be looking to jump the walls before full time, it was a reaction to the circumstances at the time when we were at Ayr.... yes there were chants of storming the pitch but that was in reference to after the match not during it...
