Really interesting new service by Met Police, enter your N4 XYK postcode and then zoom out to see the overall situation in N4. Unfortunately I cannot provide a specific link at the moment but the general website one: Crime Mapping website
From the FAQ:
What is the purpose of the new MPS Crime Mapping website?
The MPS is currently testing electronic crime mapping software, to ensure that it meets our expectations in terms of delivery to Londoners.
What do the maps show?
The site is populated with the crimes of burglary (residential), robbery (personal and commercial) and vehicle offences (“theft of” and “from” vehicles) shown as an “aggregated total” of these combined crimes.
