I was browsing through flickr and spotted another example of poor treatment of photographers. Amongst the comments, not only was there a link to the Petition to clarify the laws surrounding photography in public places but also there was a link to an Early Day Motion entitled Photography in Public Areas. As suggested by the commenter I have written to my MP via TheyWorkForYou to request his support in this matter (although having since looked at the Early Day Motions he has signed, he already has).
