MIAMI, Fla. - The U.S. Justice Department could bring a hate crime charge against the shooter in the killing of black Florida teenager Trayvon Martin if there is sufficient evidence the slaying was motivated by racial bias and not simply a fight that spiraled out of control, legal experts and former prosecutors say.
So far, only one such clue has surfaced publicly against 28-year-old George Zimmerman, the neighborhood watch captain who fatally shot the 17-year-old Martin on Feb. 26 in the central Florida town of Sanford. On one of his 911 calls to police that night, Zimmerman muttered something under his breath that some listeners say sounds like a racial slur. Zimmerman's father is white, and his mother is Hispanic.
"It sounds pretty obvious to me," said Donald Tibbs, a Drexel University law professor who has closely studied race, civil rights and criminal procedure. "If that was a racial epithet that preceded the attack on Trayvon Martin, we definitely have a hate crime."
Others, however, say the recording is not clear enough to determine what Zimmerman actually said. And many experts say more evidence would be needed that he harbored racial prejudice against black people and went after Martin for that reason alone. There had previously been burglaries in the complex committed by young black males, possibly heightening Zimmerman's suspicions when he spotted Martin.
"They are going to have to show he was specifically targeting this individual based on his race, creed, color, et cetera," said David S. Weinstein, a former federal prosecutor in Miami. "Not that he was chasing somebody down and got in a confrontation that may or may not have been based on that."
Zimmerman's parents, in a letter to a local newspaper, insisted their son is not a racist, and several black residents of the neighborhood where Martin was shot have only good things to say about Zimmerman. Zimmerman has not been charged with any crime and is claiming self-defense under Florida's "Stand Your Ground" law, which eliminated a person's duty to retreat when threatened with serious bodily harm or death. He claims Martin attacked him as he was walking back to his truck, according to police.
"He's not a racist," attorney Craig Sonner said about his client. "The incident that transpired is not racially motivated or a hate crime in any way."
Those "Stand Your Ground" laws, in place in about two dozen states, have come under increasing scrutiny. U.S. Sen. Charles Schumer, D-N.Y., on Sunday sent a letter to U.S. Attorney General Eric Holder asking for a federal investigation into whether killings are going unprosecuted because the laws put too much of a burden on local authorities.
Martin's parents and hundreds of supporters say Zimmerman should have been immediately arrested and charged with the youth's killing, but local police say they have little evidence to disprove his self-defense claim. A grand jury will be convened April 10 to consider whether to bring state charges, which could include second-degree murder or manslaughter.
After receiving a no-confidence vote from the city commission, Police Chief Bill Lee announced last week he was temporarily stepping aside from his post. The city manager, Norton Bonaparte Jr., said officials want the case to be resolved fairly.
Civil rights activist Al Sharpton, who has been appearing at rallies with Martin's parents to call for an arrest, said the Justice Department should investigate the case as a hate crime.
"Any time you have a pattern of engagement based on someone's having a particular group in mind, that qualifies for hate crime inquiry," Sharpton told The Associated Press.
The Justice Department's civil rights division and the FBI are conducting their own probe in the case, and a federal hate crimes charge could come out of that no matter what state authorities do. The hate crimes law carries a potential life prison sentence when a death is involved.
Tibbs said one key is determining whether Martin's race alone was the reason Zimmerman decided to follow him in his vehicle. Martin, who was from Miami, was staying in the neighborhood with his father and father's fiancΘe and was returning from a convenience store with Skittles and a can of iced tea when the confrontation took place. He was not armed.
"He was not suspicious. What makes him suspicious in the moment is the fact that he was black. If Trayvon Martin was white, would any of this have happened?" Tibbs said.
If Zimmerman were a police officer or a government official, he could be prosecuted by the Justice Department for using his official authority to violate Martin's civil rights. That was the case made against Los Angeles police officers who had been acquitted in state court of beating Rodney King, which sparked huge riots. Two of the four officers were eventually convicted of federal civil rights violations.
