Hundreds of photographers flooded Trafalgar Square in London today in support of the 'I’m a Photographer, Not a Terrorist!' mass photo gathering.
The gathering was a protest against the police using anti-terror laws to harass photographers taking pictures in public places.
It follows a series of detentions of photographers under Section 44 of the Terrorism Act including police detaining an architectural photographer in the City of London, the arrest of a press photographer covering campaigning Santas at City Airport and the stop and search of a BBC photographer at St Paul's Cathedral.
