How artificial intelligence could help warn us of another Dallas

As the country reels from the spasm of gun violence that killed two black men and five police officers this week, a prominent digital vigilante is using an online tool he hacked together to keep an eye on hotspots that seem at risk of boiling over into bloodshed. The Web app, which is powered partly by artificial intelligence, analyzes posts on social media as well as police radio chatter and feeds of the local airspace in virtually any region. To detect rumblings of unrest and alert the public. At the moment, the tool has its gaze trained on Baton Rouge, where protesters backed by the New Black Power Party have gathered for a rally. "I'm looking for any indication they are coordinating skirmishes … I guess I'm expecting trouble in that location, so [I] have it trained on Baton Rouge preemptively," said the creator of the site -- who goes solely by his Internet pseudonym, the Jester -- in an interview with The Washington Post.
