Scary stuff. Smart you did not go to the China national celebration. otherwise FBI can accuse you anything, spying, etc. I remember that is what they did to a Taiwan born Chinese(Wen ho lee) of spying for China & locked him up for a long time. Of course later that guy was cleared of any of the original charges. Just one minor mistake - he mishandled documents. But that happens all the time that people handle confidential documents inappropriately. A lot of people bring documents home, which they should only read in the office.
