A Parkland deputy who stayed outside a school where students and staff were being shot was shown in a special video presentation to have arrived at the building before at least a half dozen of the victims inside had been targeted by suspected gunman Nikolas Cruz.
The Marjory Stoneman Douglas High School Public Safety Commission on Wednesday saw a presentation that combined an animation showing the gunman's and victims' movements during the Feb. 14 shooting, security video of Broward Sheriff's Deputy Scot Peterson and recordings of his calls to dispatchers.
All had been previously released, but this was the first time they have been shown simultaneously.
It showed that when Peterson arrived outside the three-story building where the massacre occurred, at least six of the 17 killed had not been shot.
Peterson stayed outside the building, telling dispatchers that shots were being fired and to close down surrounding streets. Critics say he should have gone into the building to confront the shooter.
Peterson has been subpoenaed to testify before the commission next month.
The commission has recommended that at least one police officer be assigned to each of the state's public high and middle schools. But elementary schools could be protected by an armed security guard or non-teaching staff member.
The commission voted 9-5 to approve the recommendation after first overwhelmingly rejecting a proposal that all schools have at least one police officer. Opponents argued that was unrealistic because of the cost and the unavailability of police officers as the state already has thousands of openings for police officers and sheriff's deputies, without adding the need to staff schools.
Many of the state's 67 districts already have at least one police officer assigned to every high and middle school.
The sheriff leading the commission said it would cost billions to fully implement a model security plan for the state's schools.
Pinellas County Sheriff Bob Gualtieri said that adding security measures such as high-tech video systems, metal detectors and bullet-proof glass at the state's 4,200 public schools would cost more than $2 billion.
In addition, placing at least one armed police officer at each campus would cost $400 million annually.
The commission has been meeting about every four weeks since April. The members include law enforcement, education and mental health officials, a legislator and two parents of victims and they will issue a report by Jan. 1 recommending changes to the Legislature and the next governor.
