The number of “lessons to be learned” resulting from various enquiries into the conduct of public officials (mainly, but not exclusively, the police) has reached epidemic proportions. The overriding feature of very many of these (Savile, Cyril Smith, Greville Janner, Lutfur Rahman to name but a few) is that police officers were prevented by their superiors (usually under pressure from politicians) from investigating allegations made by the public for fear of rocking various boats. Savile was seen as untouchable as was Cyril Smith. Not too sure why Janner wasn’t properly investigated long before he became allegedly too ill to stand trial. Rahman’s odious activities were not investigated because the Metropolitan Police, already branded as “institutionally racist”, are terrified to do anything in areas where high numbers of minority ethnics prevail.
The only lesson that needs to be learned in all of these examples is that the police (and the courts) should operate without fear or favour, affection or ill-will. It’s not rocket science; it does not need multitudinous enquiries to establish. It is a basic principle under which any society that calls itself civilised should operate. Launching further investigations into any matters of this type will simply tie up resources which could be better employed where the results may be of benefit.
