It's a weighing of risks, really. I don't value neither airport security or my employer's secrets as highly as my own safety but will weigh in the risk as the situation develops.

If I am asked to accompany them to the dark room I'll just give up, unlock the laptop, hand it to them and then quietly inform my employer's legal team that a potential security breach has occurred (after I get safely to a hotel).

I really don't want to spend time in jail because of a nervous cop.
