Sounds sensible to me. The assumption of guilt has resulted in too many false accusations which have collapsed in court.
"Scotland Yard is to abandon its policy of automatically believing victims as commissioner Cressida Dick said 'clumsy behaviour between somebody who fancies somebody else' was not a matter for police.
Miss Dick said officers must investigate rather than blindly believe an allegation, and should keep an open mind when a victim has come forward.
'It is very important to victims to feel that they are going to be believed,' she told the Times.
'Our default position is we are, of course, likely to believe you but we are investigators and we have to investigate.'"
