The sheriff in Parkland Florida said the armed school resource deputy stationed at Stoneman Douglas High School stayed outside the building during the massacre.
Scott Israel, Broward County Sheriff said "He never went in."
When asked "What should he have done?" Israel replied "Went in. Address the killer. Killed the killer."
The sheriff stated video shows 30-year veteran Deputy Scott Peterson standing outside for four minutes. The shooting happened in 6 minutes killing 17 people.
Sheriff Isreal said "Devastated. Sick to my stomach. There are no words."
Deputy Peterson was first suspended without pay. He has since resigned.
The development comes as President Trump declares the way to stop school shootings is by arming teachers and strengthening background checks. President Trump stated "Instead of advertising 'this school has no guns, we are gun free', you let people know the opposite. You come into our schools, you are going to be dead."
The president suggests 20 percent of teachers, about 700,000 people, should be trained and armed.
Another idea, raising the minimum legal age to buy rifles from 18 to 21. President Trump said "The NRA will back it and so will congress."
The NRA quickly opposed. NRA President Wayne LaPierre said "The opportunists wasted not one second to exploit tragedy for political gain. The elites don't care not one bit about America's school system. If they truly cared, what they would do is they would protect them."
Friday, Florida Governor Rick Scott will announce what he calls an action plan to help keep students safe. Including keeping guns out of the hands of those struggling with mental illness.
