On his way back from a vacation in Iceland, WikiLeaks volunteer Jacob Applebaum was detained and searched by U.S. Customs and Border Patrol agents in Seattle today. A security researcher and Tor developer, Applebaum documents the experience -- his second -- on Twitter.

• It's very frustrating that I have to put so much consideration into talking about the kind of harassment that I am subjected to in airports.

• I was detained, searched, and CPB did attempt to question me about the nature of my vacation upon landing in Seattle.

• The CPB specifically wanted laptops and cell phones and were visibly unhappy when they discovered nothing of the sort.

• I did however have a few USB thumb drives with a copy of the Bill of Rights encoded into the block device. They were unable to copy it.

• The forensic specialist (who was friendly) explained that EnCase and FTK, with a write-blocker inline were unable to see the Bill of Rights.

• I requested access my lawyer and was again denied. They stated I was I wasn't under arrest and so I was not able to contact my lawyer.

• The CBP (U.S. Customs and Border Protection) agent was waiting for me at the exit gate. Remember when it was our family and loved ones?
