Andy Smith writes: Slashdot reported last September how I was arrested while standing in a field near a road accident, as I photographed the scene for a newspaper. I was initially given a police warning for "obstruction", but the warning was then cancelled and I was prosecuted for resisting arrest and breach of the peace. These are serious charges and I was facing a prison sentence. Fortunately we had one very strong piece of evidence: A recording of my arrest. Not only did the recording prove that two police officers' testimony was false, but it caught one of them boasting about how he had conspired with a prosecutor to arrest and prosecute me. Yesterday the case was dropped, and now the two police officers and the prosecutor face a criminal investigation.
