This video from The Guardian shows the attack on Ian Tomlinson at a G20 protest in London, shortly before he died. It shows Tomlinson, who was not part of the demonstration, being assaulted from behind and pushed to the ground by baton-wielding police.

How many others where assaulted? We’ll never know – the police did everything in their powers to keep photographers away, such as reported by The British Journal of Photography when police used Section 14 of the Public Order Act 1986 to move journalists during the demonstration. Are we on the road to a police state or am I being over dramatic.
