They're working with her to say, okay, make sure that you watch what he's doing online. If he starts fixating on violent stuff- tell us. Let's make sure we know what he's bringing back and forth to school in his backpack. Lots of measures like that. So there are protective measures, there are constructive measures, and that's how a case like this would work in a school setting.

It's different, of course, in workplace and otherwise.

I mentioned that historically because in some ways the work of behavioral threat assessment developed out of that at the FBI, which is one of several places where this work was developing in the 1980s and 90s. Historically, the FBI would try to track down unknown serial killers.

These are the famous Hollywood stories we know like Silence of the Lambs and finding the unsub, the unknown subject was the term that the Bureau used back then. That kind of work still exists, but although I think they do a lot less of it now for a set of reasons I won't get into because their technology and DNA and things like that make tracking serial killers different now.

Back then, it was trying to figure out from a crime scene, who is this person? How can we narrow a set of possible suspects?

What weird things are we finding in the crime scene that are a clue to who this person might be that combined with all the other investigation we're doing? That was the classic... serial killer hunting that became mythologized through Hollywood and popular culture entertainment, probably in some ways accurate and not. But that was about finding someone that they didn't know who it was.

This is different because there's no finding a school or mass shooter. We know who they are because they do it. You're talking about trying to predict an attack, which isn't possible. This is a minority report.

For decades, people have tried to figure out, can you predict an act of violence like this? And the answer is definitively no. There is no way to predict someone doing this, but you can prevent it if you can identify the process leading up to it. So that's what the profiling is. It's studying the process of behavior and circumstances leading up to the attack.
