Shouldn't George Zimmerman Be Required to Prove Self-Defense?

Just on the facts that they had an unarmed minor who was also physically smaller than George Zimmerman (a good 100 lbs.), a 911 call in which Zimmerman was told to get back in his truck, go to a particular location and wait for the police to arrive and not to pursue Trayvon Martin, there was probable cause to arrest Zimmerman that night.  

Zimmerman's record was frosting on the probable cause (the photo all over the news of Zimmerman is a mug shot from an arrest for resisting arrest and battery on a law enforcement officer).    

Trayvon Martin was drug- and alcohol-tested, but George Zimmerman was not, and Trayvon Martin was identified as the voice screaming for help on the 911 calls made by the neighbors.  

Witnesses also have reported that they felt pressured to corroborate George Zimmerman's account by the leading questions that police asked.  Neighbors have reported that the police didn't question them, didn't knock on doors around the scene, didn't return their phone calls. 

There's probable cause and abundant evidence of police misconduct.
