Is he talking about Major Matthew Alexander, author of How to Break a Terrorist, among others?  If so, it's possible I met Friedman, but don't remember the name.

I'm working with someone who says he met you, Barry Friedman, a descendant of William Friedman. He thinks you two attended some sort of event or meeting with Col. Alexander, but he also has a tendency to get confused. Have you ever met Col. A.?
