That's a great question, Mr. Harris. I would simply say that we at CSIS have the legislative authority to investigate threats to national security based on what's called section 2 of the CSIS Act, and you kind of just go with your gut in many ways.
I will say that we came across many cases of people who appeared to just talk the talk and then would switch in a heartbeat to actually planning something, whether it was travelling abroad to join ISIS or things like that. It's not an exact science, and this is what worries me when we try to delineate this in such ways that it's only 12 mechanisms or that it's only 12 of this. Life is, unfortunately, much more complicated than that, and I think a lot of us simply went either on our instinct or on the fact that we'd seen many previous investigations that were analogous to that.
We didn't come up with any kind of foolproof system, and I would submit to you, sir, that it's, in fact, a fool's errand to try to reduce this to something that is actually as simple as that. A lot of it is learning as you go and having the necessary resources to take a look at those people when they actually start to do or plan to do some very dangerous things.
