When a Flowery Branch student was suspected of leaving threatening comments Monday on an Instagram post, Hall County investigators were able to trace the post to the computer’s Internet provider address within hours. As social media becomes increasingly widespread, law enforcement have begun to us it as a tool for both spreading information to the public and gathering information for investigations. “We do utilize social media to receive and give information to the public, as far as from a law enforcement perspective,” Gainesville Police Department spokesman Cpl. Kevin Holbrook said.
