Half-pint HAL tips news of UK prosecution lawyers who are instructing police to study information on Wikipedia when preparing to give expert testimony in court. "Mike Finn, a weaponry specialist and expert witness in more than 100 cases, told industry magazine Police Review: 'There was one case in a Midlands force where police officers asked me to write a report about a martial art weapon. The material they gave me had been printed out from Wikipedia. The officer in charge told me he was advised by the CPS to use the website to find out about the weapon and he was about to present it in court. I looked at the information and some of it had substance and some of it was completely made up.' Mr. Finn, a former Metropolitan Police and City of London officer and Home Office adviser, added that he has heard of at least three other cases where officers from around the country have been advised by the CPS to look up evidence on Wikipedia."
