Secret Service on preventing school shootings

This 2012, two-minute video is an interview with two Secret Service researchers about school shootings. Main takeway: In almost every case of someone shooting up a school, the shooter wrote or said in advance that he was going to do it.

And so did Nikolas Cruz, quite a long time before the Parkland, Fla., massacre. But the question is begged, if one of the most important ways to stop these shootings is to report to the authorities, then are not the authorities obligated to take steps?

When it came to the Parkland horror, apparently not. The literally years-long prequels to the massacre were filled with warnings that were, in some cases, deliberately ignored.

There were multiple warning extending back to early 2016 that Cruz was a threat to human life and safety

The Miami Herald:

The rage and obsession with violence documented by Cruz’s therapists during nearly two years of interactions when he was 15 to 17 years old continued through his school career: Again and again, authorities were warned about the teen’s explosive tendencies and lack of impulse control. Again and again, authorities ignored the warnings.

In addition to the troubling behavior Cruz exhibited at the schools he attended — including an incident in which the teen reportedly brought a backpack with bullets to class — law enforcement officers were also alerted that Cruz might be dangerous.

The FBI failed to act on two tips about Cruz, one of which involved Cruz posting online that he planned to become a “professional school shooter.” The Broward Sheriff’s Office was also warned about the teen, and had received a report that he “planned to shoot up the school.”

The FBI failed and has admitted to it. They failed so severely that Fla. Gov Scott called for the director's resignation.

The Broward County sheriff's department failed many times, especially after being specifically warned that Cruz would become violent very soon.

The school system could have had Cruz arrested, but did not because he was named Cruz.

The Broward County school board knew of Parkland shooter's obsession with guns and violence, documents show.

Stoneman HS administrators  themselves failed to take action in advance of the shooting..

Deputies visited Cruz's home on police business 45 or more times in the preceding few years.

911 audio of Deputy Peterson's radio transmissions provably show that he lied when he said post-event that he thought the shots were coming from outside the school.

Three other deputies arrived and took cover behind the cars and did nothing.

EMTs have said on the record that deputies prevented them from entering the school to begin treating and evacuating wounded. (Link is to local reporter's Twitter feed.) Also here.

So Cruz killed 17 people and wounded 12.

Reporting threats to the authorities only works when the authorities do something about the report. For the Parkland shooting, the authorities failed at literally every level. One has to ask: if they were going to design a system to fail on purpose, what would they have done differently from what they did do?
