Amnesty International works tirelessly to document human rights abuses in all of the other conflicts you mention and has done for many years. What exactly is your point?
How is it possible an organization that documents human rights could mislead the world? Any government PR firm, backed by CIA or MI6 can create a list of "witnesses" and have them testify to AI. My point is, just because AI is documenting it, it doesn't mean it's legit. Especially around Syria since there is a lot of documented story fabrication.
