 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 .
