It happened to me for the first time on my last flight leg - I unpacked my
suitcase (checked) and found the note that it had been "inspected".

I guess I have a few questions:

1. What do they do when they inspect a bag? Do they handle your stuff?
I had some plastic bags inside my suitcase with the clothes in them, and I
couldn't tell if those were opened/closed or never opened.
(All of the clothes went right into the laundry just in case.)

2. Do they select bags randomly? If not, what criteria do they use?

3. Is there some record of what bags are searched in case something turns
up missing from a bag? (This did not happen in my case.)

4. Does anyone know - when does this inspection happen? One would hope
that it is before loading, if they think they might find something bad.

5. Are all passenger-checked bags X-rayed also anyway? If so, what is
the purpose of the opening/searching process on top of that? (Or rather,
if it is necessary, why do it so sporadically?)

Thanks for any answers!!
