I understand this operation (ie the list of names supplied to the UK police, following an FBI internet 'sting') is prioritising investigations, according to the occupation of the suspects. Accordingly, police officers and others in positions that might bring them into contact with children are being targetted first. As the police get further down the list, I'm sure we will see other branches and trades of the armed forces featuring in the press, in similar circumstances, in the next year or so.
Good to see they are getting results, but not good publicity for the RAF.
