The Crime Mapper enables Londoners to keep tabs on crime rates in their respective neighborhoods. A map shows the number and type of offenses committed.

Flo Heiss: “A lot of people hated this site when it first hit their browsers – mainly because it didn’t really work at first. When the UK police opened up their crime database’s API, so many people typed their postcode into the search box that the site totally crashed. Some of the results are not entirely accurate, so am told, but I applaud the spirit of this effort. I like what it represents. Openness.”
