You are equating City fans as equal to dippers there not. It happens year on year with them and it is accepted by all their fans that it will happen. You rarely hear a dipper complaining about their own fans, they always blame the authorities. Jibbing is treated as a joke, forgery is expected, if the genuine ones don't kick up a fuss then yes they deserve it.So, if someone gets a fake copy of your ticket, and the police tell City that it's happened, but they let in the faker, and then make you queue for 3 hours, and then don't let you in. That's your problem? Because you support the same team as the person with the fake ticket?
I appreciate that Liverpool fans have a reputation for using fakes/jibbing, but that doesn't mean the people who bought genuine tickets and had a shit time, deserve it.
