Ten months after a student killed 17 people in a shooting at Parkland, Florida’s Marjory Stoneman Douglas High School, a panel tasked with reviewing what went wrong is releasing its findings.

The state commission investigating the Feb. 14 shooting released a draft report this week that blames the tragedy on numerous failures by school officials and the Broward County Sheriff’s Office, and suggests arming teachers as an effective way to protect students against attacks, the South Florida Sun Sentinel reports.

“In an ideal world, we shouldn’t need anyone on campus with a gun, but that’s not the world we live in today,” said Polk County Sheriff Grady Judd, one of about 20 lawmakers, educators, politicians, and parents on the Marjory Stoneman Douglas High School Public Safety Commission. “One’s not enough. Two’s not enough. We need multiple people in order to protect the children.”

The commission voted to include the suggestion in the 407-page draft report, with the caveat that teachers toting guns should go through a selection process, background checks, and training. Currently, Florida allows some school employees including administrators, librarians and others, to carry a firearm as part of a guardian program, but expanding that to include teachers would require legislative approval, according to the news site.

The report shows deputies wasted time arranging equipment and bulletproof vests instead of rushing inside the school once the shooting started, while school staff bungled the emergency response by leaving doors unlocked and failing to effectively broadcast the “Code Red” alert.

Radio communications were also a jumbled mess, while commanders on scene failed to give clear orders. One disgraced former BSO deputy even ordered officers to stand down, though some disregarded the directive to save students.

“Broward, do not approach the 12 or 1300 buildings,” Scot Peterson, the school’s resource officer who retired after the shooting, said over the radio, according to the report. “Stay at least 500 feet away.”

Some heeded the call, others didn’t.

BSO Capt. Jan Jordan and Lt. Mike DeVita cowered behind a patrol car during the shootout. Others including Deputy Danny Polo formed a team and rushed past the two to storm the school, according to McClatchy.

The report contends six deputies who waited or hesitated outside the school “appear to be in violation of accepted protocol under which the deputies should have immediately moved towards the gunshots.”

Many interviewed for the report recalled a scene of mass confusion and miscommunication. Radios malfunctioned, response vehicles jammed roadways, and a 20-minute delay in surveillance footage meant the shooter was long gone as police continued to search the school, according to the report.

“There was abundant confusion over the location of the command post and the role of the staging area. This stemmed from an absence of command and control and an ineffective radio system,” the report said.

The commission released the draft in Tallahassee on Wednesday, and it’s expected to submit the final report to the governor and state legislature by the end of the year.

The draft called for improved communication between agencies and pointed to 69 documented incidents in which the accused shooter threatened or hurt someone, talked about guns or weapons or raised other concerns over the last 16 years. It also suggested an internal investigation into the actions of seven deputies who failed to help, but did not call for expensive security upgrades like metal detectors or bulletproof glass, the Sun-Sentinel reports.

“We will use it as a basis to conduct our own thorough investigation, and we’ll take appropriate steps to make any necessary improvements,” Broward County Sheriff Scott Israel, who was widely criticized for his department’s failures, said in a prepared statement.

State Rep. Jared Moskowitz, who represents Parkland, said the report will also inspire changes in the next legislative session.

“The only one responsible for what happened is the parkland shooter, but several significant government failures contributed significantly,” he said. “The legislature is going to look for accountability on that.”

Many on the commission are adamant that schools, including educators, should also have the ultimate authority to hold school schoolers accountable, as well.

“We have to give people a fighting chance,” commission chairman, Pinellas County Sheriff Bob Gualtieri, told McClatchy, “we have to give them an opportunity to protect themselves.”
