I'm somewhat surprised that if they are known turnstile jumpers that there is no action being taken in respect of that, either by the police and/or Palace themselves.
Palace's own statement on the turnstile jumpers: "This kind of antisocial and criminal behaviour is completely unacceptable and we condemn it in the strongest possible terms. There are very clear images of the incident and we will work with the police to identify the supporters involved, who will face stadium bans as well as potential criminal proceedings."
I am not surprised since despite the rhetoric nobody has face charges for forcing their way into the ground. Not one... Given previous examples of this when the plod cant use the actual law they often push their luck as much as possible and football fans are an easy target.
