Cincinnati City Council approved $264,000 last year so the fire department could buy new bulletproof vests. That was after bullets whizzed by a medic on Kenton Street near McGregor Avenue in July 2016.
About eight months later, a man in Northside shot at firefighters who'd come to his home to check on him. The man's friends grew concerned when he didn't answer his door and called for help. Prosecutor Joe Deters called the gunfire a result of a "misunderstanding," because the man thought the firefighters were intruders. He wasn't charged.
