I really think you overshoot here on almost every point. The ones that stick out for me: * Not everyone has trained overseas. In the west/east bubble maybe that's common, but nowhere else.

* You seriously try defending reading bomb-making books? To imply that reading a book on how to make bombs, without any background need for it like a job related to pyro, etc., is not suspicios is IMHO rediculous.

* Not "everyone" uses encryption. Actually, the majority of web users do not, and less so knowingly.

* Not "everyone" will suddenly and completly change the overall theme of themselves.

* Not "everyone" has recent loss or has been humiliated.

In general, your other points are getting onto something and i somewhat agree.

However, to be honest I don't think a break down approach is the best to gain incite into the FBI's process. The questions are supposed to be treated as a whole, not singulars. Each question is not designed to give a yes/no answer; but rather the end result, suspicion of terrorism, is a complex, non-analytic function of all the answers
