A Chicago police 911 dispatcher is slamming Second City Mayor Lori Lightfoot over the city’s out-of-control crime wave, calling her “a disgrace” for mishandling the crisis. Dispatcher Keith Thornton, who went off on a viral online rant last week, said on “Fox & Friends” Tuesday that Lightfoot has turned Chicago into “a death zone” by failing to back cops, adding, “the blood is on her hands.”
