U.S. Tightens Security on Electronics at Overseas Airports

In 2010 (in a TSA Blog Post since deleted[1]), the TSA responded to the accusation that they were copying files from passengers' electronic devices by saying that they don't even turn electronic devices on. So #1, this is a policy (informal or not) reversal.

The tin-hat in me wonders if this is paving the way for TSA to start to demand access to information on electronic devices.

I also wonder what "power on" means—do I have to have a BiOS or bootloader installed? Does a HDD-level encryption have to be bypassed to make sure it "works"?
