Eyewitnesses confirmed bloodshed in the Square! (Score 1)

Since when was Wikileaks the authorized source of truth? Eyewitnesses and journalists present at the massacre have stated that there was bloodshed at the Square. Why should I believe some anonymous Wikileaks document over other testimony? For example, Chinese-Canadian Journalist Jan Wong wrote about the incident in detail in her book "Red China Blues." Granted, she could have been lying, but give me a reason I should believe Wikileaks over her.
