I didn't feel good about it when I found out (actually, the moment I signed the lease), but there was nothing I could do about it.
My exit from Vietnam was almost humorous. I had about 50 DVDs in my suitcase, mostly encrypted backups and burned movies, and every single one was inspected by sight, holding it up to the light (to see how far the burn went?), then left on the floor of the airport for me to pick up. Upon re-entering the US, the customs officers did almost the same thing, and then just confiscated all my discs.
Weirdly, no one on either side checked my laptop.
