A few freepers have been knowingly re-posting it (and others). Your guess as to their motive is as good as mine.
Does the same hold true of the pictures of Zimmerman or is that another George Zimmerman?
Is this a picture of 17 year old Martin? Do you have a picture of the 17 year old Martin? Do you have any guess as to what ABC's movtive is to post this photo?
The initial impression for me is of a young child being killed by some guy who is pictured in what could be an orange jump suit that you usually associate with being in prison.
