A cool new crime map to play with

Real estate website Trulia.com just launched an interactive crime map that's intended to be an improvement upon what other sites offer. Here's their pitch:
Trulia's new interactive Crime Maps let you explore, compare and comment on crimes across America — right down to the time of day, specific intersection and type of crime committed. In the past, simple-to-decipher crime reports haven't been readily accessible to the public, which we thought was an unfortunate problem. So we fixed it! Now whether you're interested in just the facts or want the story from folks who live there, Trulia's Crime Maps can help you make better decisions about where to live.

Assuming the data is accurate, it's actually pretty useful. When you click on the black dots (which represent the number of crimes in a general area over the course of a month), a window like the one below comes up, detailing the types of crimes, the names of the neighborhoods in which they were committed, and the intersections (roughly) at which the crimes took place. The stats were updated as recently as May 14:

The color coding is done on a curve — an explanation of their methodology says, "The color scale is relative ... the top 5% of blocks with the most crime density are colored dark red across every city, the next 5%-10% of blocks are light red while the next 10%-20% of blocks are orange, etc." — so it's obviously not intended for city-to-city comparisons.

According to the site, Atlanta's three most crime-ridden intersections are Capitol Avenue SE & Martin Luther King, Jr. Drive SE; Holley Street & Howell Mill Road; and Lenox Parkway & Lenox Road.
