Peter Van Buren is being investigated by the US Department of State, whom he works for. What did he do? He blogged. Van Buren posted a link to a publically available WikiLeaks diplomatic cable. He also wrote a book.
“Two years ago I served 12 months in Iraq as a Foreign Service Officer, leading a Provincial Reconstruction Team. I had been with the State Department for some 21 years at that point, serving mostly in Asia, but after what I saw in the desert — the waste, the lack of guidance, the failure to really do anything positive for the country we had invaded in 2003 — I started writing a book.” – Peter Van Buren
