In the hours and days following 7/7, the police appealed for both photographs and video recordings made by the general public in relation to the attacks. Why would such an appeal be made unless photography by the general public has a part to play collecting evidence and therefore help maintain security?
IMO, we, as in genuine LU enthusiasts, are TfL/LU's greatest supporters. Any behavior that intentionally rejects our role as enthusiasts, recorders, intelligence gatherers, of what happens on the LU system, would represent a naive, outragous, immature and grimly silly response.
There are numerous times when I have approached TfL/LU staff about characters behaving as they should not (passengers stuck on a train at Barking sidings), (smoking weed @ Hornchurch - when I was prepared to pull the lever on a train).... I could go on. If TfL/LU wishes us, a huge ally (the enthusiast community), to disengage, IMO they would be outragously stupid to block us from recording what is happening on the railway...
After all, how can anyone record suspicious behaviour, if we're banned from recording in the first place !!!
As someone with a monthly column in one of many railway magazines available at all good newsagents, I would shout very loudly if enthusiasts (that followed the rules) were told by TfL officially (not just by uninformed station staff) that photography on LU was now banned on security grounds !!
