The story is here:
Both agencies, like many other police departments throughout the country, have long used computer mapping programs internally to detect crime patterns, develop strategies and determine how to deploy officers. In recent years they have been experimenting with ways to make crime data available to the general public in bulk, electronic form — often hiring outside companies to build online crime maps or, in some cases, posting raw crime data online that can be downloaded.
The Times' crime mapping program, which debuts Thursday, goes a step further, allowing users to analyze crime statistics, search historic crime patterns and receive alerts when several crimes occur in an area over a short period of time. As is common practice when releasing information about reported crimes, the LAPD and Sheriff's Department provide the block where a crime occurs, instead of the exact address.
