The usefulness of this "trick" relies on not having the _data_. They aren't going to hit me with a wrench for the decryption password to a cloud-stored blob that's not on the device (and ideally, one they don't know about. Remember the password and the location of the data. Remember to secure-delete it from your device though. There should be an easy "prep for border crossing" checklist that includes this.)
