Absolute Bol***ks!
The parade was in the public demain so there is no reason why anyone should be stopped from taking piccies.
I guess the thought is along the same lines as children who are in the school environment or perhaps at a leisure centre.
Re your Lurgan approach I guess they were considering someone photographing a station for subversive reasons.
If the photographer was detained in London I suggest he give his solicitor a call for his illegal detention.
I would LOVE someone to challenge me in such a case
