News is that Us Agents now have the power of seizing your notebook, if you were traveling to the USA, and they can hold your notebook for an undisclosed period of time according to a report from the Department of Homeland Security.
These precautions are put into place to stop "terrorism" and the information can be shared with any of the US agencies to "help the fight". The policies cover hard drives, flash drives, cell phones, iPods,
pagers, beepers, and video and audio tapes — as well as books,
pamphlets and other written materials.
The policies require federal agents to take measures to protect
business information and attorney-client privileged material. They
stipulate that any copies of the data must be destroyed when a review
is completed and no probable cause exists to keep the information.
