(NEW!) Go through airport security with an encrypted laptop, sensitive information and free conference stickers showing your affiliations as an activist. Let airport security confiscate your laptop. Airport security drugs and wrenches you. You give them your laptop password. The police arrests you based on suspicions of terrorism.

Voila, when the school principal snatches your unlocked laptop while you’re in the lib, all your pirated hentai becomes permanently unaccessible whether you give up the password or not. [Edit: the USB key is strapped to your wrist]
Note: luks uses 2 encryption keys, where one is randomly generated and encrypts the actual data, and the second one is given by the user and encrypts the first one; luksErase destroys the luks header containing that first key
