Ars Technica has a pretty nice summary article on a few crime mapping and mashup sites around the web. We’ve reported one or two of these in the past, but there are a few I hadn’t heard about. It’s interesting to see Toronto releasing all if its homicide information on the web for all to see. It isn’t real accessible for sucking up into a subsequent mashup, but it would be interesting to see someone do the translation. London did a better job this summer by going ahead and linking crime data to the map. This type of stuff is full of potential for participatory GIS type work and more responsive government. If anyone know of any others like this (crime or otherwise), please make note in the comments, as its a particular interest of mine!
