Look at the controversial Zimmerman trial. If you took what you were hearing from the media at face value he is guilty as sin, shooting down a frightened teen carrying his skittles and soda home to his little brother.
The last part of that has been proven true, but the fact is that Martin was not a scared little boy. The media purposely and willfully manipulated footage and continues too, so that Martin is perceived that way. I have no doubts that the family of Treyvon Martin will always view him as the young man depicted in the media after this tragic event, however the media did no one any favors by fueling this case with lies and innuendo.
