According to the last edition of the Open Data Barometer, only 17% of surveyed governments had, by 2017, made any crime data available to the public as open data. Outside of the publication of administrative data by police forces, usually at the local level to enable crime incident mapping, the release of open data from judiciaries or other entities within the justice system remains rare, and governments are generally more reluctant to open up crime and justice data to the public. 2Yet despite this strong beginning, crime and justice probably remains one of the least developed sectors for open data. Not only did this inspire a plethora of diverse mapping mash-ups, 1but it also sparked many other data-driven crime maps and acted as a key reference point for early open data arguments. In May 2005, a month before the official Google Maps application programming interface (API) was launched, was launched, a pioneering experiment that took crime data from the Chicago Police Department and presented it on an interactive map.
