Frankly it was the first time I've ever come into contact with an FBI agent. He was extremely polite. Very nice young man. He did make it clear that I did not have to cooperate at all if I didn't want to, but I certainly would never stand in the way of such an investigation. After all, who would want to obstruct justice?
But that's all I have to say on the matter. I won't comment any further. Just thought some of the devoted would like a little red meat to gnaw on for a while. :-)
