"The video speaks for itself", the Sheriff's office said in statement that also included the surveillance video. "His actions were enough to warrant an internal affairs investigation, as requested by Sheriff Scott Israel on February 21".
The video footage, along with audio dispatch records released last week, calls into question Peterson's statement and actions.
"What I saw was a deputy arrive at the west side of Building 12, take up a position and he never went in", he said. Broward County Sheriff Scott Israel has said Peterson stayed outside the high school during the attack, instead of going inside to confront the gunman.
The video starts about a minute after the suspect, Nikolas Cruz, began firing his semi-automatic rifle, according to the timeline released by the Sheriff's office.
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". He said the question is why he didn't: was it because of Peterson's individual character or something about the culture in the Broward Sheriff's Office that made him avoid a deadly force situation?
But they do expose the 54-year-old Peterson's failure to respond, authorities say.

Broward County Circuit Judge Jeffrey Levenson, in an eight-page order released Monday, said the videos could be released without imperiling the school's security system or endangering the investigation into the massacre.
As CrimeOnline previously reported, Broward County Sheriff Scott Israel announced a week after the shooting that Peterson had chosen to resign, after he learned that his response to the shooting was being investigated.
