The Broward County Sheriff’s Office has identified to Fox News the captain who, according to sources, directed responding deputies and units to “stage” or form a “perimeter” outside Stoneman Douglas High School, instead of rushing immediately into the building, as the mass shooting unfolded there. Multiple law enforcement and official sources said the commands in the initial moments after Nikolas Cruz allegedly opened fire would go against all training which instructs first responders to “go, go, go” until the shooter is neutralized. As law enforcement arrived, the shooter’s identity and exact location were still unknown.
