>> An armed the deputy who failed to confront the gunman in last week's deadly Florida shooting resigned Thursday. Scott Peterson stepped down rather than face suspension after an internal investigation showed he did not enter the school when the rampage began in Parkland. He was the only law enforcement officer present.
And police say, a video showed him take a position but never go into the school.>> Scott Peterson was absolutely on campus through this entire event. He was armed. He was in uniform.>> And when the local sheriff was asked by reporters what Peterson should have done?>> Went in, addressed the killer, killed the killer.
>> Officials are looking into whether more could have been done to prevent the shooting that killed 17 people. They say former student and suspected gunman, Nicolas Cruz, is still the priority. Authorities have said that Cruz made his getaway moments after the shooting by blending in with the students fleeing the school.
As police arrived on the scene, they thought the gunman was still inside. Based on a security camera feed, they thought showed them real time images, but it was a footage from 20 minutes earlier.>> It added to some confusion when it comes to that, because the officers that are in the school trying to find him were given inaccurate information.
>> Police insists the mishap put no lives in danger. Two other deputies have been placed on restricted duty over their responses to a number of calls and reports about Cruz received by the local sheriff's department over the course of a decade.
