I haven't seen the video or read much about it, but I was told something similar last week.

Police are currently finding difficultly proving they are Brighton supporters. Throughout the 90's it's been established they were Manchester United supporters, before becoming an on/off Arsenal fan. They settled on supporting Chelsea for a short while but now dependent on the day of the week they seem to be either followers of Manchester City or Brighton.

Questioning revealed they go to the Amex to get behind Brighton or Hove for at least 75 minutes most weeks before leaving early in the hope of getting some lovely photos of locomotives travelling through Falmer Station for their Instagram.
