And Winsor isn't going to be a senior police officer...
One thing any outsider might ask is why E&W forces persist with their separate systems. Scotland has had a national intelligence system for years now, it isn't perfect and had teething issues, but is certainly a model to borrow/build on. The single Scottish force is going to bring all sorts of lessons in administration amalgamation. Only the most hard core Not Invented Here Syndrome sufferer would fail to try to draw lessons from that.
British policing has built some impressive and national systems in the past. HOLMES 2 for instance, and good old PNC.
You're quite correct, however I was careful not to use the term "senior police officer" in my post. However, I did use the term "senior officer" which of course he will be, as all of Her Majesties Inspectors of Constabulary are "Inspecting Officers" and since he's applied for the top job there, he will be a "senior officer".
You're right that police IT systems that are national would be a better solution, however I think the fact that many of these systems are integrated with other local systems, with each force making different requirements on the systems and that many of the contracts with suppliers and service providers have fixed terms, often ending at different times makes this an enormous task. Just look at the NHS national IT systems fiasco. I think that the idea is good, but it will be a massive job and maybe cost prohibitive in these austere times.
