Wait a minute: father named "Pearlman", son named Gadahn?
Another article I read indicates that the father changed his name when he ventured out into the countryside to get close to nature. As best I can tell, these people were the quintessential Kalifornia Fruit Flakes.
No offense Sauron.....but I'm thinkin this guy is the "Mouth of Sauron" (Assume you've seen or read LoTR?)
