It turns out that the woman giving directions belongs to one of the Communist groups organizing the rally -- if her t-shirt is to be believed, since it depicts the flag of Communist Vietnam, which has been frequently displayed by such groups at protest rallies in the U.S. for decades.


The San Francisco Chronicle featured the original photograph on its front page in order to convey a positive message about the rally -- perhaps that even politically aware teenagers were inspired to show up and rally for peace, sporting the message, "People of Color say 'No to War!'" And that served the Chronicle's agenda.

But this simple analysis reveals the very subtle but insidious type of bias that occurs in the media all the time. The Chronicle did not print an inaccuracy, nor did it doctor a photograph to misrepresent the facts. Instead, the Chronicle committed the sin of omission: it told you the truth, but it didn't tell you the whole truth.

Because the whole truth -- that the girl was part of a group of naive teenagers recruited by Communist activists to wear terrorist-style bandannas and carry Palestinian flags and obscene placards -- is disturbing, and doesn't conform to the narrative that the Chronicle is trying to promote. By presenting the photo out of context, and only showing the one image that suits its purpose, the Chronicle is intentionally manipulating the reader's impression of the rally, and the rally's intent.

Such tactics -- in the no-man's-land between ethical and unethical -- are commonplace in the media, and have been for decades. It is only now, with the advent of citizen journalism, that we can at last begin to see the whole story and realize that YOU - the public has been manipulated like this all along.
