Open Data and Crowd Sourcing meeting to fight against crime

It would be nice to have some numbers / a scale on the map to interpret what red means. Seattle has twice as much crime reported as Boston, yet Boston looks redder.

Nice use of open data, I can see this very handy when you are looking for an apartment or a house. The baltimore crime map is also very interesting.

UI is nice & clean although I did not understand right away what the service did. Maybe a tag line would help.

How did you find all the open data and is there cities that you couldn&#x27;t do because of that?<p>The rendering is really nice!
