As someone who has had years of experience working with intelligence officials and writing on terrorism, I find amateurs like yourself quite amusing. As an obvious FBI apologist, I have one caustion: Please don’t read Bill Gertz’s “Braakdown.” If you do, you will have one.
There's the old saying, those can't, teach, those who can't teach, write.
While you were allegedly writing about "terrorism", I was actually working as a military prosecutor, and have been involved in the prosecution of several sailors charged with violating Art. 106a. I'm not sure what you've read or written to make you think you're a "professional", but your comments here don't lend yourself much credibility. Just sayin'.
The FBI watched a cell of foreign intelligence operatives for close to 10-years without detection and that is nothing short of AMAZING. The fact that you don't understand that very elementary principle tells me all I need to know about your "expertise".
