Fla. school officer waited outside building for 4 minutes as killings happened, sheriff says Deputy Scot Peterson resigned after he was suspended without pay.

 -- A Marjory Stoneman Douglas school resource officer has been suspended without pay after Broward County Sheriff Scott Israel said video shows him taking up a defensive position during the shooting but never entering the school.

Israel announced Thursday that the decision to suspend Deputy Scot Peterson was made after reviewing video from the shooting and taking statements from witnesses and Peterson himself, Israel said.

“He should have went in, addressed the killer, killed the killer,” Israel said.

Peterson was armed and on campus during the shooting, Israel said. Since he met the requirements for retirement, Peterson opted to resign after he was told he was being suspended, Israel said.

Israel said that the video shows Peterson arrived at the west side of Building 12, where most of the killing happened. He then took up a position but "never went in."

The video shows that Peterson remained outside the building for upward of four minutes during the shooting, which lasted about six minutes, Israel said. Aside from getting "on his radio," Peterson did "nothing" while standing outside the building, Israel said.

When the shooting started, Peterson was in an office dealing with a "school-related issue," Israel said.

When asked by reporters to describe how the video made him feel, Israel responded, "sick to my stomach" and "devastated."

"It doesn’t matter who went in first, it doesn’t matter in what order you went in," he said. "What matters is that when we in law enforcement arrive at an active shooter, we go in and address the target and that’s what should have been done."

Peterson was named school resource officer of the year in the city of Parkland in 2014, after he had been with the school for five years, records show. According to a booklet announcing the award, Peterson had been "proven to be reliable in handling issues with tact and judgment" and was active in mentoring and counseling students that year.

Peterson was also nominated for Parkland deputy of the year in 2017, an internal memo from the sheriff's office dated March 27, 2017, shows. He started his career with the Broward County Sheriff's Office in 1985.

The personnel file on Peterson shows he completed multiple training programs as well, including a mandatory firearms training program and special tactical problems training program.

Two other deputies were placed on restricted duty while the sheriff's office investigates whether they "could've" or "should've" done more while dealing with suspect, 19-year-old Nikolas Cruz, amid the 23 calls they received involving Cruz or his brother since 2008, Israel said.

Of those calls, investigators feel that two cases "deserve extra scrutiny" to see if there was a policy violation by the deputies involved.

Cruz was arrested shortly after the shooting and is charged with 17 counts of premeditated murder. He is being held in a Broward County jail.

On Wednesday, Israel announced that Broward County sheriff's deputies would now be carrying AR-15 rifles on school grounds within the district, adding that one of the ways to make schools safer is to evaluate the number of school resource officers on campuses.
