I'm a member of an interesting, friendly and helpful photography website called Phototopix. Recently, one of the members posted a link to invite photographers to sign a Downing Street petition, requesting the Prime Minister "...remove new restrictions on photography in public places..."
The restrictions seem to be yet another government knee-jerk over-reaction to circumstances; another means of restricting 'normal' freedoms under the misleading and inappropriate cover of "prevention of terrorism." As one of the Phototopix members wrote, if we were taking photographs for terrorism reasons "...we wouldn't stand in the street with a DSLR with big zoom lens... would we???
No reply required. I do invite you to sign the petition for photographers' freedom, and for common sense. Just visit the Number 10 Petitions website. I joined as no. 6094.
