Media bias will be the reason for the riots. Had the media reported fairly from the beginning by showing recent and respectful pictures of both Martin and Zimmerman (saw a NY Post story during the trial that was still using the Martin picture from when he was twelve or so), had they not doctored the phone calls to make it sound like Zimmerman was racial profiling, using racial slurs, and all the misinformation about him disobeying the 911 operator, if they had given recent height and weight measurements then maybe, when Zimmerman gets off, there wouldn't be riots.
