Yeah, so just to continue on the, we call them indicators or warning signs.

Yeah, absolutely.

So we talked about grievance, which is almost like a staple thing that you'd expect in most cases.

There's some cases where mental health is the issue or dominates the issue.

But even some of those, there's still elements of grievance, but some not.

So it's just to kind of caveat that slightly, but...

We talked about tipping points, flashpoints.

Those are things to be concerned about.

And what I'd say about that is if you already know someone has a major grievance and talking about kind of taking action and then there's a major event in their life or around the world, then…

that's when you should be concerned.

Whether you know them as a friend, family, or whether you're part of an agency, it's the same difference.

Because once you get those things, it tends to accelerate.

That's in the cases that we know about.

We talked a little bit about preparation.

This is the idea that someone has to plan this and they might do it over a week or longer, sort of more meticulously, but often it's only a few days and you might get strange behaviors and reconnaissance.

But one of the things I'd flag is that this is real world and online.

So often you also get preparation online or comments online.

Someone might be in a forum and someone's talking about doing something.

And what I'm interested in, I suppose, is if you saw that as a member of the public,

you might think, oh, that's weird, and not do anything about it.
