There was just a story in the Washington Post about an app designed to curb shoplifting by encouraging people to “report suspicious activity” in Georgetown, a DC shopping district. The article revealed that it was rife with racial profiling. The app had user input content but I think similar concerns were brought to light. https://www.washingtonpost.com/local/georgetown-social-network-accused-of-racial-profiling-is-suspended/2015/10/19/7a8865a2-7674-11e5-b9c1-f03c48c96ac2_story.html
