Repeal the discretionary powers for an officer to arrest photographers.
Any real harm to be done with a camera is already covered by 'materials useful to terrorism' or espionage legislation.
Why does this idea matter?
When I saw officers indecently assaulting an arestee, then deliberately knocking to the ground a member of the public with a land-rover, my camera stayed in my pocket as I knew I would be next to get stripped in public and bundled into the vehicle.
The IPCC failed to respond to a complaint accompanied by a written description of the events.
The current legislation, much like the terrorist stop and search powers are being abused as a convenient 'discretionary' excuse.
