Anti-social Behaviour, Crime and Policing Bill

The Obscene Publications Act was very much on my mind as well. Very often this material is generated by the offenders themselves and is privately retained, so I think it would fall foul of some of the definitions in that rather elderly piece of legislation. The material that is obtained can sometimes be used as incriminating evidence to help prove the general character and intent of individuals with an interest in child abuse, who are sadly far too prevalent. Do the police find difficulty in using that material as incriminating evidence, or do they want more information?
