Broward County’s firefighter-paramedics are used to wearing protective gear for battling blazes. Now they’ll be getting new protection — body armor vests and helmets — for when they’re assisting victims in incidents involving guns or other dangerous weapons. It’s a sign of the times, officials say, with the proliferation of active shooter and mass casualty cases across the country, including deadly incidents at Fort Lauderdale-Hollywood International Airport in January and at the Pulse nightclub in Orlando last year.
