Long the focus of attention, the national news media's persistently inaccurate photographic portrayals of slain Florida teenager Trayvon Martin appear to have clearly influenced one of the witnesses in the trial of his killer, George Zimmerman.

While NBC News's dishonest editing of an audio clip of Zimmerman appears to have only temporarily skewed public opinion, during testimony last week it became apparent that the national media's continual showing of photographs of a much younger Martin led witness Jeannee Manalao to incorrectly believe that Zimmerman (who is 5'8") was taller than Martin (5'11").
