Power Taskforce's ideas on crime maps

The Home Office is confirming that it’ll press ahead with online crime mapping, as recommended by today’s Casey Report on Engaging Communities in Fighting Crime.
Even better, the Power Of Information taskforce – specifically Will Perrin and Tom Loosemore, in apparent association with designers Schulze and Webb – have posted a few concepts showing not only the mapping of crime data, aggregated to postcode sector; not only an overlaid layer of data showing public facilities such as schools, pubs and cash machines; but also the ability to actually do something as a follow-on. I’m especially intrigued by the RSS icon: blogging bobbies, perhaps?

Judging by the mockups anyway, we’re looking at some serious interaction potential: polling on local priorities, emailing the local policing team or your local elected representatives. (Never mind the possibility of interacting with the data.)
It’s not the first time some/most of this has been proposed: whilst working at National Statistics, I was involved in the concept work which ultimately led to the disappointing Neighbourhood Statistics. It’s not as if we didn’t have some of these same ideas… but mashing-up has come a long way since then, thanks particularly to Google Maps. I note the ‘presumption’ that Google’s technology would underpin these maps… another nail in Ordnance Survey’s coffin?
