A video from Marjory Stoneman Douglas High School on the afternoon of the Valentine's Day massacre shows former school resource officer Scot Peterson responding to the shots fired, but it doesn't provide much in the way of detail.
Authorities previously said the footage showed that Peterson never went inside the building where the gunman was shooting at students and school staff.
Well, the surveillance footage of former Broward County Deputy Scot Peterson on the day of the tragic Marjory Stoneman Douglas High School in Parkland, Florida as been released.
A Florida judge earlier this week agreed with news outlets that the video should be released, despite resistance from police and school officials who felt it should have been held as evidence in an active investigation.
After speaking into his radio, Mr Peterson can be seen making his way to the building where students were being murdered in a golf cart.
The Broward Count Sheriff's Department issued a statement about the release of the video, which the department did not appeal.
Sheriff Scott Israel blasted Peterson eight days after the shooting, saying the deputy should have 'went in, addressed the killer, killed the killer, ' saying the apparent inaction left him 'devastated.
Peterson was suspended and then resigned his post, and in a statement released by his lawyer said that he thought the gunfire originated from outside and reacted accordingly by waiting for the suspect there.

Trump appeared to relish his visit to the border wall prototypes, pointing eagerly to charts and graphics shown to him. The state is at the vanguard of resistance to his administration's immigration policies.
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 - appear to be moving about frantically on a lawn.
It begins shortly after gunfire erupted, with Peterson and civilian security monitor Kelvin Greenleaf walking with objective outside an administration building, clearly alarmed by sounds.
Peterson also told other law enforcement officers who raced to the school to stay outside.
His attorney Joseph DiRuzzo claims that Peterson believed the shots were outside; adding that he had been following his training by "taking cover and prompting a lockdown". For a period of time, Peterson is obscured by a pole. The video released Thursday did not have sound.
While outside, Peterson provided frequent updates on police radio, according to a timeline provided by the sheriff's office, including directing other officers to the building on the large campus and asking for nearby streets to be shut down.
The Florida Department of Law Enforcement is reviewing the police response. The sheriff's office, meanwhile, ultimately reversed course and said it supported making the footage public. Most of the recording above comes from one stationary camera on campus, and the sheriff's office released the video after being ordered to do so from a judge.

Levenson ordered the sheriff's office to release a version of the video with "the identities of the students and unknown witnesses" removed between noon Thursday and noon Friday.
