Good point! It could be Iraqi funded terrorists (AQ or some other group with close ties to Iraq)
IMHO, I think that it probably is a sleeper cell of AQ, just beginning. That is the part that scares me!
Why haven't the police or FBI given the public the decription of the sniper? I keep reading that they have some idea of what he looks like, seems to me that would be helpful for the people that live in the area.
