You could be right. Assuming EOM is telling the truth and he really is here.
As a American-born translator, Gadahn/EOM would know about Al Qaeda's planned operations. And EOM's warnings, references to "Amerikkka", and pre-9/11 warning via heavy metal are consistent with Gadahn's manner.
Plus from his posting today:
"You watch picture ashcroft show you on tv you see EOM. ha ha."
EOM=Gadahn
