The mail recently had the story "PCSOs 'solve crime every six years", it's a fine example of the fact that when it comes to the Daily Mail, we just can't bloody well win. For years we have heard calls for "more bobbies on the beat" the government come back with Polics Community Support Officers as a solution.
As far as I can tell, these officers do exactly what you would expect from a bobby on the beat, patrol the streets, providing a visible police presence to reassure local residents. Now it appears the Mail is jumping on unfavourable statistics. Statistics it's all to happy to discredit when convenient.
Police out on foot patrol don't tend to detect crimes going on since most people on seeing a police officer or similar don't commit crimes. Thats just common sense, the effect of police officers on patrol is something that can't easily be measured. So it's not surprising that the statistics don't show very much.
Surely the fact that PCSO's are walking through crime free streets is a good thing though.
