What's really new?
The Met have had a crime figures website for a while, in fact it's linked as 'Detailed Crime Figures' off the new one. What's new - the whizzy Google maps stuff and the coloured areas for the hard of thinking, plus it goes down to subward rather than ward level. What's missing - quite a lot of types of crime (anything except burglary, robbery and vehicle crime) and per-month comparisons so you can see trends instead of being mislead by statistical spikes from one year to the next (June 2007 had twice as many murders as June 2008, but that doesn't mean the murder rate has halved).
A cursory glance shows that crime is reducing, on the whole, nearly everywhere, but that the 'high' category covers a huge range of possible values. The boundaries are entirely arbitrary, in fact, and some explanation of how they're set would be nice.
The main problem with it is comparing dissimilar areas using the crude measure of crimes per x people - the West End is a crime hotspot on this, presumably because it's got a lot of robbery crimes committed against people who are visiting, rather than locals (pickpocketing, in other words). This skews the figure a bit, because the resident population is relatively low. It indicates a crime problem, but not one that local residents need worry about overly or one that should affect house prices (which are astronomical there anyway).
Also, it's mid-August now, and neither site has figures for July up yet...
