You're seeing what you want to see, and what the chaps at FAC want you to be outraged by. The DCC is explaining that the police have a job to do and do it in a certain way, e.g filming and using the footage to assist in future arrests. If they didn't do it that way then the alternative is to resort to violence to achieve the arrests. In no way is he saying that's what the police want to do or that it's in any way likely to happen. I note so far on this thread that nobody at all has suggested any reasonable and practical solutions to any of the problems the police have to deal with at matches, other than to bizarrely be less heavy handed while at the same time stop simply observing offences and do something about them.
