Read Greenwald's entire post for a summary of other instances in which the U.S. government has detained foreign nationals without trial, only to later release them. For example:
" Khalid El-Masri, a German citizen who alleges -- with the support of German
prosecutors -- that the U.S. Government abducted him, drugged him, flew him to
multiple different torture-using countries (and shuttled him at least to Kabul, Baghdad, and Skopje, Macedonia) as part of the administration's "rendition" program, only to then release him after five months when the U.S. realized it had abducted the wrong person."
then there is the case of Mustafa Osama Nasr, who was abducted by the CIA off the streets of Milan and flown to Egypt to be tortured, which prompted Italian prosecutors to issue arrest warrants for the 13 CIA officers responsible for this kidnapping within Italy.
Juxtapose these cases with other headlines from this week such as "U.S. Holds AP Photographer in Iraq 5 Mos" and "U.S. war prisons legal vacuum for 14,000.", and it's hard to miss Greenwald's point, isn't it?
