Drone-detecting devices deployed in New Jersey within the past week have shown little to no evidence of anything nefarious or threatening. That's according to New Jersey Gov. Phil Murphy, who said Monday that 12 sightings of suspected drones were reported in the state overnight Saturday and one on Sunday. Federal officials say there is no evidence that drones are being operated with bad intent or by foreign governments, and many sightings over the eastern U.S. have actually been of manned aircraft that look like drones. A large number of mysterious drones have been reported flying over New Jersey and across the eastern U.S., sparking speculation and concern over where they came from and why. Gov. Murphy and U.S. Sen. Andy Kim have both gone out on drone hunts, hoping for answers. The FBI, Homeland Security, state police and other agencies are investigating. Murphy and law enforcement officials have stressed that the drones don’t appear to be a threat to public safety, but many state and municipal lawmakers have nonetheless called for stricter rules about who can fly the unmanned aircraft — and to be allowed to shoot them out of the sky.
