Centralisation is the problem, not the solution
The increasing distance between public servants and the public they serve is the problem here. In the case of the police they have become increasingly centralised and increasingly remote. Fifty years ago there was a police house in every village and policeman in every village. Now, my town of 30,000 doesn't even have a permanent police presence. The station is closed at night, because, of course, no crime ever happens at night, does it? Officers have to come from 9 miles away.
A centralised police computer system (another massive public sector IT project, of course) isn't going to resolve the core problem with policing which in my opinion is that police are too far divorced from the communities they are supposed to serve.
This IPPR report is par for the course for them, unfortunately. New Labour apparatchiks to a man and woman (and, of course, funded by generous donations from the willing taxpayer), they believe that greater control over the public services will improve the quality of those services. Of course, the more they tighten their grip, the more services will slip through their fingers...
