interesting that they showed up in the middle of the night if he is being cooperative.  Seems you know nothing about this type of raid.  Like searching a place for drugs, these surprise raids are done to people that are hiding something.  Also, cooperating in the past is fine, but certainly they now believe he's hiding something or some documents.  Cmon Golfinguy, put on your thinking cap, and start paying attention to the disaster that is unfolding right under your nose.  You're definitely back on my really stupid list.
