Zimmerman is in fact 'a creepy cracker'.

The truth can also be inconvenient: by virtue of his actions and character, George Zimmerman is in fact a "creepy cracker."

The origins of the word cracker are uncertain. What we do know is that Trayvon’s use of “cracker” drew on a long history of mass racial violence by whites against African-Americans that began with the transatlantic slave trade and the plantation system in the “New World.”

 “Cracker” is evocative of the sound of the whip, wielded by a white overseer or slave owner, as it lashes and tears black flesh. Cracker is a word that embodies white on black racial violence and tyranny.

Cracker is in no way equivalent to the word nigger.
