In May 2009, the Court of Appeal ruled that photographs collected by FITs of people who have not committed a criminal offence can no longer be kept. The ruling was made after Andrew Wood, an arms trade activist, was photographed after challenging the management of Reed Elsevier at their AGM over them organising arms trade exhibitions. Wood argued that police had harassed him and infringed his right to privacy by photographing him. Lord Collins of Mapesbury said that the police presence had a "chilling effect" on people who were protesting lawfully. FITs have not been banned but they must now justify the retention of photographs on a case-by-case basis. As a result of the ruling the Metropolitan Police's public order unit, CO11 was forced to delete 40% of the photos of protesters that it held.
