Over the past week we have published a number of posts to present our conclusions and recommendations to the technology for transparency movement by focusing on specific categories of projects: aid transparency, budget monitoring, election monitoring, civic complaints, and parliamentary informatics. Those five categories encompass the vast majority of projects that we documented throughout our research. However, there are five other categories of technology for transparency projects that are also worth reviewing from a thematic perspective. A number of websites have cropped up over the past few years in the United States and United Kingdom to add transparency and accessibility to crime reports from municipal police departments. CrimeMapping.com, Oakland Crimespotting, CrimeMapper, LAPD Crime Maps, CrimeReports, SpotCrime, Crimedar, and EveryBlock (which began in 2005 as ChicagoCrime.org) are just a few such examples. Outside of the United States and United Kingdom the majority of crime mapping projects seem to be based in Latin America, which claims 8% of the world's population, 40% of world's homicides, and 66% of kidnappings. WikiCrimes.org is a collaborative, global, multilingual mapping of crimes around the world that is built with WikiMapps software. It was conceived by Vasco Furtado, Professor at the University of Fortaleza, Brazil where he coordinates a research group in “Knowledge Engineering.” All data can both be imported and exported in the open standard KML format. WikiCrimes currently has 13,117 reports of crime, almost all of which are based in Brazil. Reports can be filtered by category, time, and credibility. Users can sign up for notifications of crime reports based on their customized filters, and there is a beta mobile application available in Portuguese. All crime reports are ranked by their number of views, comments, and confirmations, and are re-distributed via Twitter. Users can confirm crime reports by linking to relevant news items or video and photographic evidence of the actual crime. So far the most commented crime is a homicide that took place on March 29, 2008 at 11 in the evening in Sao Paulo. It has received 22 positive confirmations, one negative confirmation, and four comments. Delitos Ecuador is a project of Fundapi which uses Ushahidi to collect and aggregate crime reports in Ecuador. Reports can also be submitted via Twitter using the hashtag #delitosEC. The Illegal Drug Trade Map in Argentina combines a blog with a Google map. It was created by the Argentinian Association Against Drugs and enables citizens to learn more about the illegal drug trade in Argentina, and to submit locations where they have seen drug dealing take place. Panamá Transparente uses Ushahidi to aggregate and map reports about crime in Panama. Iluminemos Mexico is a citizen network against violence in Mexico that maps crimes and invites users to discuss and implement solutions to internal security problems. Outside of Latin America, Sithi is a Cambodian human rights portal that aims to crowdsource and curate reports of human rights violations across multiple human rights organizations. Recommendations: While most crime mapping websites in the United States visualize official crime data from municipal police departments, which can then be confirmed and commented on by users, all of the crime mapping projects we documented depend on individual citizens to provide the information. This is likely due to the fact that police departments in most of the world still do not publish their crime reports, much less in a structured format that can be automatically mapped and re-purposed. We recommend to crime mapping project coordinators that they work in collaboration with local police departments in order to automate the publishing of official crime data. If a project has successfully convinced a police department to publish its crime reports, we suggest that they publish their experience to help provide like-minded projects with an advocacy strategy. While mapping crime helps us better understand both where it occurs and how crime spreads over time, it does not necessarily lead toward pro-active solutions. In fact, it can even lead to paranoia and social exclusion if residents react by merely investing in higher walls and more expensive alarm systems. Crime mapping platforms should focus on prevention as much as after-the-fact reporting. We recommend that they integrate their content with social groups that are working in neighborhoods where crime is prevalent and youth are at risk.
