Report highlights sheriff’s office’s failures in Parkland shooting.

School deputy Scot Peterson not only hid as a gunman shot down students inside Marjory Stoneman Douglas High School in February. He stayed there for 48 minutes, according to a report released Wednesday.

The draft report of the Marjory Stoneman Douglas High School Public Safety Commission highlighted multiple failures by the Broward Sheriff’s Office, among them deputies who failed to rush in and commanders who failed to take charge.

Peterson, who was allowed to resign within days of the massacre, was the first on the scene.

“Peterson never made any effort to enter [the school] and help rescue victims or seek out the suspect,” the report said. He never left his safe spot “despite an overwhelming law enforcement presence for over 30 minutes.”

Peterson, a law enforcement officer for 32 years, was the only person on campus with a gun when former student Nikolas Cruz arrived. He was not wearing his ballistic vest, the report said. His last active training had been two years before, on April 19, 2016.

He responded to Building 12, scene of the attack, one minute and 39 seconds after the first shots were fired — after 21 people had been shot. Nine of them would die.

“This makes clear that seconds matter,” according to the report.

The commission recommended that school resource officers like Peterson receive “frequent, thorough and realistic training to handle high-risk, high stress situations.” They typically are not faced with situations such as domestic violence calls, robberies and shootings, the report said, so proper training is of “utmost importance.”

But Peterson wasn’t the only one from the Broward Sheriff’s Office to hear the gunfire and stand back, the report said. He was one of eight deputies and sergeants from the agency on the scene early and “none of these BSO deputies immediately responded to the gun shots by entering the campus and seeking out the shooter,” the report said. One of them bypassed the high school completely, according to the report.

The commission criticized Capt. Jan Jordan, the local commander, for her first radio transmission, which was: “I know there’s a lot going on, do we have a perimeter set up right now and everyone cleared out of the school?” She was “not focused on the primary objective of an active shooter response: Seek out the killer and eliminate the threat.”

The commission also found that Jordan “spent approximately the first seven minutes after her arrival in the Building 1 office and then transitioned to a position of cover in the north parking lot behind a car.” She resigned last month.

In addition, law enforcement officers within Building 12 became confused over which classrooms had been cleared and which rooms had not, the report said. The commission criticized the sheriff ’s SWAT team for using a color-coded glow stick method to mark certain rooms.

“The inherent shortcoming in that system is that the glow sticks can easily be kicked out of place,” according to the report. “BSO needs a more effective system for its SWAT Team to denote cleared room than glow sticks.”
