No other deputies are seen in the video released Thursday. "By not telling the [officers that] shots were fired from the building, he made it sound like the shooter was out of the school", former Coral Springs Police Officer Tony Pustizzi told the Sun Sentinel.
After police reviewed the surveillance video, Peterson was placed on unpaid leave. Peterson, seen in a dark green uniform, quickly turns and jumps into a golf cart to investigate.
During much of the time the shooting was taking place, Peterson was obscured from view by a pole.
Judge Elizabeth Scherer then entered the not-guilty plea on his behalf for 17 counts each of first-degree murder and attempted murder for the February 14 shooting spree in Parkland. He also radioed the sheriff's office, issuing a warning about the incident. Broward County Sheriff Scott Israel has said Peterson stayed outside the high school during the attack, instead of going inside to confront the gunman. But a detailed timeline released last week by the sheriff's office, based on radio dispatches and surveillance footage, showed Peterson said over police radio that the blasts were coming from "inside".
His attorney, Assistant Public Defender Melisa McNeill, reiterated that Cruz would plead guilty if prosecutors waived the death penalty, which they refused to do. He was suspended and resigned, but is still under investigation.
The angle of the remaining footage shows the two pull up to the southeast corner of Building 12 as what appears to be a group of students - the images are blurred under orders from the judge - seem to be moving about frantically on a lawn.

You see Deputy Peterson and another person on the campus responding.
Since then, Mr Peterson has fought back on the characterization of him as a coward, saying through that he had provided valuable help to the special forces team that entered the building.
The video does not show inside the buildings, the gunman or the faces of any students.
The release of the footage comes one day after National Walkout Day, where survivors of the shooting and students nationwide walked out of their classrooms to send a message something needs to change when it comes to school safety and gun laws.
