This is all i could find:
Guantanamo Bay detainees captured on the battlefield - Wikipedia, the free encyclopedia
It shows qty. 2 people
i guess we want to help China also...
As of 2008 roughly 55 detainees were cleared for release but werent because they couldnt be repatrioted in China, being they were training to fight for independence from the Chinese gov't, China wants to take action against them so we keep (kept?) them locked up. They are ethnic Uyghurs. I remember at one time (if not still) these Uyghurs made up the majority of the people in Guantanimo bay (source: Wikipedia)
Some others are in Guantanimo for training to join other rebellions such as the Chechens
I guess then by "innocent", people mean they are terrorists who were planning to attack someone besides the U.S.
