(I meant to type CPS, not CPR in my last post!)

From watching the many programmes on TV about the activities of the Police (especially Channel 4's '24 Hours in Police Custody') I've concluded that it is rather difficult to persuade the CPS to agree that a case should be undertaken and a prosecution set in motion, unless one has all the necessary evidence, reliable witnesses, acceptable motive and so on..

This is as it should be of course, but it must result in quite a few instances of potentially guilty people being set free.

The Police probably know full well a miscreant is guilty, and must get very frustrated with the system.

Free Press and open reporting is worth safeguarding. We have a right to know what's going on. But not flying a helicopter over a person's property after an apparent 'tip-off'. That's a bit sensation-seeking and shady in my view.
