Since the Met Police - responsible for protecting people and investigating crimes against them - failed miserably to investigate an alleged rape in 2004 by a taxi driver, who then went on to repeat his crimes many times until he was finally caught in 2008 despite being interviewed by police in 2007 - is it such a surprise that such offences go either unreported or un-investigated in the military?
John Worboys in case you don't remember his string of offences.
