Thank you, Mrs. Stubbs.
You know, it really sounds simple, folks, but you go where the information leads you. I think the problem is that, if you go in with preconceived notions, you start making errors. I wrote about this a lot in my very first book, The Threat From Within. If you assume from the outset, for example, that poor socio-economic status is a large contributor or predictor, you'll find out that you're wrong as many times as you're right.
The bottom line is that we entrust our law enforcement officers and security intelligence officers to gather the information and see where it's going to take them, and to try to make decisions based on what they're actually seeing, as opposed to some kind of pre-arranged framework. By saying this, I'm not pooh-poohing the work done by academics such as Monsieur Geoffroy. I think it's very valuable, but those of us who work in security intelligence, in all honesty, didn't have the time to incorporate those theories, because we were too busy doing investigations. Were they helpful? Yes, they were, but they didn't frame or dictate the directions in which we took our investigations.
I'm not sure if that helps to answer that question, but you're right that it is extremely complicated and each case is different, unfortunately.
