The grumbling of local EMTs who responded to the scene of the school shooting at Marjory Stoneman Douglas High School has grown to a crescendo with a new report from FOX News that says they were initially barred from entering the building and providing care to the wounded.

Citing numerous sources, the report states the Broward County Sheriff’s Office ordered at least some of the emergency responders not to enter the building. FOX News also notes this could be part of an additional investigation into the incident that isn’t directly involved with the massacre itself.

The BCSO issued the following statement over the weekend:

“There are multiple investigations being conducted in addition to the Stoneman Douglas shooting. Investigators will not be rushed or asked to jump to conclusions. Their investigations are thorough and methodical as they take and compare witness statements, review dozens of incident reports, transcribe and analysis numerous radio transmissions, listen to more than 80 911 calls.”

According to FOX several sources noted police were bringing victims out to EMTs in the initial stages of the response. That report supports an earlier news story from a local reporter who interviewed an EMT who was on the scene, who said:

“Everything I was trained on mass casualty events says they did the wrong thing. You don’t wait for he scene to be cleared. You go in immediately armed. Retrieve the victims. You can’t leave the victims laying there.”

The EMT said he could only “hypothesize,” but believes he could have saved lives if he had been allowed inside. He added he was “eager” to go in, even if it risked his own life, to help the wounded, and he was “frustrated the entire time” he was on the scene.
