The Hamilton County, Tenn., Sheriff’s Office will begin using drones to gather evidence for court cases, detect bombs and find missing persons. However, Hamilton County Sheriff Jim Hammond assures the public the equipment will not invade people’s right to privacy. Hammond spoke Monday at a news conference to announce plans to use the unmanned aircraft systems (UAS). The Sheriff’s Office is among more than 80 law enforcement agencies, colleges and other government agencies across the country that have been granted or applied for permits to fly the aircraft, according to a Hamilton County Sheriff’s Office news release. Hammond said Hamilton County’s Office of Emergency Management and Homeland Security also has the equipment.
