According to Zimmerman's father, the story George gave the police, and which the police have described as totally consistent with the evidence - is that he lost sight of Martin, but Martin then approached HIM. I'm paraphrasing now, but Martin said, "Do you have a problem?" Zimmerman said, "No." Martin said, "You do now" - and slugged him in the face, breaking his nose and sending him to the ground. He then climbed on top of Zimmerman and started banging his head into the sidewalk. Zimmerman struggled to back up into the grass, and screamed for help. A girl who saw all of this ran into her house to get her parents - at which time the shooting occurred.
If this is true, and the police say the evidence and witnesses are supporting it, then Martin was absolutely the aggressor.
