Likewise he was held in Quantico Brig from July 2010 to April 2011, which is half again what you claim. His treatment was bad enough that it's not as if you have to lie about it to make your point.
Likewise, he was under formal charges since July 5th, 2010, and has been under the most-recent set of charges since March 1, 2011.
Likewise again, his detention has nothing to do with NDAA. A civilian court could just as easily remand someone to custody for the entire duration of a trial, even if it takes awhile.
All of this is easily available on Wikipedia. Now I'll add some hyperbole: Are there any Manning supporters who don't have to resort to misleading people or to outright lying?
