FORT LAUDERDALE, Fla. — Newly released surveillance videos show what was happening outside Marjory Stoneman Douglas High School while Nikolas Cruz was killing 17 students and staff, shedding light on the actions of law enforcement officers.

The videos were released Thursday.

Deputy Scot Peterson, the school resource officer, resigned after being suspended by the Broward Sheriff’s Office for failing to confront the shooter.

Through his lawyer, Peterson released a statement last week saying that he initially thought the shooter was outside, saying that’s why he didn’t enter the building. But Peterson’s own radio transmissions suggest he had focused on the 1200 building, according to the Sheriff’s Office.

The Florida Department of Law Enforcement, at the request of Gov. Rick Scott, has opened an investigation into the law enforcement response to the shooting.

The videos were made available in response to a lawsuit from the Sun Sentinel, the Miami Herald and CNN against the Broward Sheriff’s Office and the School Board of Broward County.

The media organizations said the public had a right to see the videos under Florida’s public record law.

A Broward circuit judge on Monday authorized the release of the videos.
