Meanwhile, the argument continues over whether the police were right to seize film in this particular instance. According to Cloke, there were two violent incidents that might have been filmed by Williams and Williams may not even have been aware of the fact that he had filmed one of them.
Williams agrees that this is possible, but remains sceptical. He told us that he has had film or cameras seized by police on three previous occasions. In one case, a complaint went as far as the Independent Police Complaints Commission (IPCC), who agreed that the police had not dealt correctly with his initial complaint.
The matter was bounced back to the police, who continued to claim that they had been entitled to remove his camera, agreed that a common assault might have been committed against Williams by the police officer involved, but as six months had elapsed - the police took eight to nine months in all to deal with the matter - no further action could be taken.
In the most recent case, he says that he was told that his film was required as possible evidence of a violent assault when "someone in an invalid carriage drove over an officers foot". However, he believes the reasons given by police for taking his film are retrospective justification and their actions were actually motivated by spite.
Williams' film remains with the police forensic unit, where it has languished for the last week, and will be returned to him when they have cleared their current backlog and managed to take a look at it.
