SANFORD, Florida (CNN) -- Worshippers in cities nationwide were wearing hoodies to church services Sunday to honor Trayvon Martin, a Florida teenager shot to death last month by a neighborhood watch volunteer.
Martin, 17, was wearing a hoodie when he was killed February 26 as he walked back to his father's fiancee's house in Sanford, Florida, after a trip to a convenience store. Police say he was unarmed, carrying a bag of Skittles candy and an iced tea; he was shot by George Zimmerman, who claims he was acting in self defense, according to authorities.
Zimmerman has not been charged in the case.
Ebenezer Baptist Church in Atlanta and Middle Collegiate Church in New York are among the churches planning to honor the teen Sunday.
"I will also preach in a hoodie. We are doing this not for show, but to send a message that all humanity is sacred. And by saying all, we are including African-American boys and girls, and men and women who reserve the right to wear a hoodie in the rain and not be racially profiled and killed because bigots think that their appearance is suspicious, or threatening," the Rev. Raphael G. Warnock said in a statement posted on Ebenezer's website.
A "Hundred Hoodie March" will take place Sunday in Rockford, Illinois, as well as a "Million Hoodie March" in Rochester, New York.
In Sanford, a "prayer for peace" and a candlelight vigil will take place Sunday evening. Another candlelight vigil will take place at the Civil Rights Memorial in Montgomery, Alabama.
"The public has had enough of the police and prosecutors operating in secrecy when it comes to people of color, especially African-Americans," said J. Willie David III, president of the Florida Civil Rights Association, the group planning the Sanford vigil.
The case has sparked a national debate over the Florida law and concerns about racial profiling. Martin was black and Zimmerman is white Hispanic.
The attorney for Martin's family, meanwhile, said bringing a federal hate crime charge against Zimmerman will be "a challenge, to put it lightly."
Daryl Parks told board members of the National Association of Black Journalists (NABJ) on Saturday that prosecution on the state level stands a better chance.
"Most state laws tend to be better for the prosecution of state crimes. And that's why we see the federal authorities expressing, although gently, in their statements that they can only do so much if there's some type of race statements involved. The state officials don't have that problem," Parks said.
"I think the focus is not necessarily a federal arrest over a state arrest. We want an arrest, period. And I think that the state aspect of that is the one that's most feasible, most attainable in this matter."
Parks said there is evidence that the Twin Lakes homeowners' association told residents who saw suspicious activity to call George Zimmerman if they could not contact the police, according to an NABJ statement.
The Martin family plans to pursue a civil case against the homeowners' association, Parks said.
Demonstrations have taken place nationwide over Martin's death.
"We as a nation have become much too violent," theRev. Jesse Jacksonsaid Sunday. "...If it's black on white, it's jail time. If it's white on black, it's revolt time. If it's black on black, or white on white, or brown on brown, it's Miller time."
After a rally in Virginia Beach, Virginia, Ron Campbell told CNN's iReport the case has not been handled properly.
"That is why we have so many protests," he said. "It was a senseless situation."
A handful of members from the New Black Panther Party rallied in Sanford on Saturday and offered a $10,000 reward for Zimmerman's "capture."
"It's time for us, as black men, to take justice in our own hands. If you won't give us justice, we will have to take justice," said Florida organizer Mikhail Muhammad. "An eye for an eye. A life for a life."
The New Black Panther Party, which the Southern Poverty Law Center describes as a "virulently racist and anti-Semitic organization," is distinct from the better-known Black Panther Party, founded in the late 1960s.
The city of Sanford responded to the bounty offer by calling for "calm heads and no vigilante justice."
"Attempts by civilians to take any person into custody may result in criminal charges or unnecessary violence," it said in a statement.
Zimmerman's attorney said Sunday that after reviewing Florida's "stand your ground" law, he believes it applies to the situation and that his client is innocent.
Initially, lawyer Craig Sonner said last week the law was "not really applicable to this case. The statute on 'stand your ground' is primarily when you're in your house."
"This is self-defense, and that's been around for forever -- that you have a right to defend yourself," Sonner said earlier. "So the next issue (that) is going to come up is, was he justified in using the amount of force he did?"
The 2005 law allows people to use deadly force anywhere they have a right to be if they have reasonable fear an assailant could seriously harm them or someone else.
It also eliminated a long-standing "duty to retreat" in the face of imminent harm, asserting that would-be crime victims have the right to "stand their ground" and "meet force with force" when attacked.
Asked Sunday about the New Black Panther Party's offering a reward for Zimmerman's "capture," Sonner declined comment.
The Sanford Police Department said officers were prohibited from arresting Zimmerman the night of the shooting because physical evidence and testimony supported his claim that he acted in self-defense in accordance with Florida law. The police department gave the explanation to City Manager Norton Bonaparte, who included it in a letter to the community about the case, posted on the city's website.
Zimmerman said he was driving in his gated community when he saw Martin walking and called 911 to report a suspicious person.
Zimmerman told the dispatcher he was following the boy, but the dispatcher told him that wasn't necessary. Moments later, several neighbors called 911 to report a commotion outside, and police arrived to find Martin dead of a gunshot wound.
Sonner says his client was injured that night and went to the hospital with a broken nose and a serious cut on the back of his head.
Sanford police said Zimmerman did not indicate a chase, telling them instead that "he had lost sight of Trayvon and was returning to his truck to meet the police officer when he says he was attacked by Trayvon," the police said in the letter posted by Bonaparte.
Florida Gov. Rick Scott has formed a task force to review the law in the wake of the shooting. Scott told CNN's "State of the Union" on Sunday that he met with Martin's parents Thursday to "let them know that I appointed a new state attorney and introduced them to the Florida Department of Law Enforcement agents that are working on the case."
"Your heart goes out to them because...no family ever imagines this could happen to their child," the governor said.
But theRev. Al Sharptonsaid he doesn't think Zimmerman was simply protecting himself.
"This is not about self-defense. This is about a man deciding somebody, based on who he was, was a suspect and that he would take matters into his own hands," Sharpton told a crowd in New York on Saturday.
Sonner said he believes Zimmerman's life is in danger and has advised him to keep a low profile.
"This case is spinning out of control," he said. "I hope there's a way to rein things in so it doesn't become an issue of a racial battle. I hope that things come back so that there can be a time for justice and for healing and not for just skipping the whole judicial process and going straight to sentencing."
