Judge weighing whether to give Zimmerman bond

Zimmerman's defense also played videos of Zimmerman talking and showing his injuries after the shooting. Attorneys then spent time questioning Kevin O'Rourke, a Sanford firefighter and emergency medical technician who responded to the shooting scene. Attorneys asked questions about the extent of Zimmerman's injuries, particularly how much blood was on his head and face.

"A good 45 percent of his head and face were covered with blood," O'Rourke said.

Zimmerman has been charged with second-degree murder for fatally shooting 17-year-old Martin on Feb. 26 at a gated apartment community in Sanford. Zimmerman has pleaded not guilty and claims the shooting was self-defense under the state's "stand your ground" law.

Martin's parents and supporters claim the teenager was targeted because he was black and Zimmerman started the confrontation that led to the shooting. Zimmerman's father is white and his mother is Hispanic.

The 44 days between the shooting and Zimmerman's arrest inspired nationwide protests, led to the departure of the Sanford police chief and prompted a U.S. Department of Justice probe.

Zimmerman's attorney has argued in court papers that he is no threat to the public and proved he wasn't a flight risk by returning to jail when his bond was revoked. O'Mara also argued that the bulk of the more than $200,000 raised by the website has now been turned over to a third-party administrator and Zimmerman has no control over the money.
