During the a bond hearing at the Seminole County Criminal Justice Center in Sanford, Fla., George Zimmerman took the stand and apologized to Trayvon Martin’s parents for the death of their teenage son. The State Prosecutor immediately confronted him.
It is unbelievably dangerous for a defendant to deliver testimony at a bond hearing.  However Mark O’Mara outlines motivation below.

In further developments an exclusive photo obtained by ABC News shows blood trickling down the back of Zimmerman’s head from two cuts. It also shows a possible contusion forming on the crown of his head. The original police report that night notes that the back of Zimmerman’s head was wet, and that he was bleeding from the nose and head.

Zimmerman was treated at the scene by paramedics, then cuffed and driven in a police cruiser to the Sanford police station. He was questioned for hours and later released. In police surveillance video obtained last month by ABC News, Zimmerman’s wounds are not apparent, and there were no bandages on his head.
The person who took the photograph of a bloodied Zimmerman, asking not to be identified, told ABC News exclusively that they did not see the scuffle that night, but did hear it. The person recalled seeing Martin’s prostrate body on the wet grass and said the gunpowder burns on Martin’s gray hoodie were clearly visible.
The photographer said that after the shooting, Zimmerman asked the photographer to call his wife. When the photographer asked him what to say, Zimmerman blurted out, “Man, just tell her I shot someone.”
Investigators have seen the photo.
Crump, the Martin family attorney, is skeptical.
“How bad could it have been if they didn’t take him to the hospital [and] didn’t stitch him up,” he said in a statement to ABC News in response to the image. “The special prosecutor has seen all the evidence and still believes George Zimmerman murdered Trayvon Martin.”  (more)
