I think it is so sad that this has happened, as expressed by others it is the minority and they are not fans but thugs. They should be put somewhere horrible and the key thrown away..........there is no way that they should be shown any compassion or lenency if they are caught.
It really is about time the british government stopped pussyfooting around and did something to punish people for the crimes they commit. I'm sure the police must be so frustrated at their lack of powers to deal with these thugs. Can't call them animals as animals don't act like that.
