May I ask my right hon. and learned Friend about cases that the CPS decides not to pursue? Is he aware of the deep frustration felt by police officers who have spent a long time preparing what they regard as open and shut cases, only to find that the CPS does not appear willing to pursue them, for reasons unknown to the police? What would be his advice to a police officer who has been frustrated in that way? Should he turn to his Member of Parliament, as he has in this case, or is there a better procedure that police should pursue? Should it not be the CPS's objective to ensure that the police officer concerned in a case has a full understanding of how and why it has behaved on that case?
