MARK HERR: "Remember your right to remain silent."

The judge said there was enough evidence to move forward with the case. He told Mr. Zimmerman that he will be officially charged during an arraignment hearing on May twenty-ninth. A hearing is set for next Friday on the possibility of releasing him from jail on bond.

Defense lawyer Mark O'Mara said Mr. Zimmerman would plead not guilty but he worries about getting a fair trial.

MARK O'MARA: "We need to calm this down and this case needs to be tried in a courtroom."

The shooting happened in the gated community where the girlfriend of Trayvon Martin's father lives. Tracy Martin and Trayvon’s mother, Sybrina Fulton, accuse Mr. Zimmerman of targeting their son because he was black. They led the protests to have him arrested.

SYBRINA FULTON: "We just wanted an arrest and we got it."

Police did not charge Mr. Zimmerman earlier because of a Florida law known as "Stand Your Ground.” It says people have a right to meet force with force, to stand their ground and not turn and run. The Florida legislature passed the law in two thousand five.

Many other states have similar laws. Supporters say these laws can reduce violent crime and protect citizens who are trying to defend themselves. But Daniel Gross with the Brady Center to Prevent Gun Violence told members of Congress that the Florida law needs to be examined closer.
