Dear Mr Pearson,
I think you should listen to this; it is an interview with a former London police officer who describes an investigation into a paedophile ring that was cancelled the night before arrests were planned. The policeman names the senior officer involved “House”, that would be Sir Stephen House, now Chief Constable of Police Scotland.
Quis custodiet ipsos custodes?
Another example of why we need a nation (uk)-wide overarching and transparent public enquiry. There has been criminal wrong-doing in covering up paedophilia for many years; this appears to have involved senior police officers: We will not make progress with protecting children until the law enforcement establishment is cleared of those blocking proper investigation.
Carry on the fight
