All Orlando Fire Department emergency vehicles are now equipped with bulletproof vests and helmets specially designed for firefighters and medics responding to mass-casualty incidents and active violent crime scenes, and Orange County Fire Rescue is planning to do the same. After last year’s June 12 Pulse shooting that killed 49 and injured more than 63, Orlando-area officials and first responders gathered to brainstorm how to best address what OFD Chief Roderick S. Williams calls a “changing dynamic.” “Orlando is not a fluke,” Williams said. “[Mass shootings are] a new norm of today’s society.”
