If I can follow up, I only have a minute left with a more specific question along the same lines.
Is there a pattern, a profile—not to say a stereotype, but a propensity—that's identified so far that raises the risk of being radicalized or being recruited, in terms of socio-economic status; in terms of racial, religious, or cultural background; in terms of networks that one does or doesn't belong to? Is there anything yet that we can use as a sort of marker for the way forward?
