After a year and a half of living as a hermit, George Zimmerman emerged from a Florida courthouse a free man, cleared of all charges in the shooting of 17-year-old Trayvon Martin.
His brother said the former neighborhood watch volunteer was still processing the reality that he wouldn't serve prison time for the killing, which Zimmerman, 29, has maintained was an act of self-defense. A jury found him not guilty of second-degree murder late Saturday night and declined to convict him on a lesser charge of manslaughter.
However, with many critics angry over his acquittal, his freedom may be limited.
"He's going to be looking over his shoulder the rest of his life," Robert Zimmerman Jr. said during an interview on CNN.
In Sanford Florida, police stepped up their presence overnight, and earlier this week the police chief went door to door seeking calm.
CBS News Reporter Pete Coombs says it appears to have worked, with relative peace in the streets.
The NAACP National Convention begins Monday in Orlando and their reaction is expected to be critical of the verdict, but on the streets of Sanford there were no riots.
Demonstrators upset with the verdict protested mostly peacefully in Florida, Milwaukee, Washington, Atlanta and other cities overnight and into the early morning Sunday . Additional demonstrations were scheduled across the country through Sunday evening.
(CBS) Protesters angered by the acquittal of George Zimmerman held largely peaceful demonstrations in at least three California cities, but broke windows and started small street fires in Oakland, police said. There were also reports of small, largely peaceful demonstrations in cities across the country.
The gatherings Saturday night in California ranged from a few dozen to a couple hundred people turning out to protest the verdict in the Florida courtroom over the death of Trayvon Martin, and police said some of the demonstrations continued into the early hours Sunday.
The Oakland police dispatch office said about 100 people protested, with some in the crowd breaking windows on businesses and starting small fires in the streets. As the protest wound down with the crowd dispersing, the office said that as of 2 a.m. PDT it had no word of any arrests.
Local media reports said some Oakland marchers vandalized a police squad car and police formed a line to block the protesters' path.
The Oakland Tribune said some windows on the newspaper's downtown offices were broken, and footage from a television helicopter show people attempting to start fires in the street and spray painting anti-police graffiti.
Protesters also reportedly burned an American and a California state flag and spray painted Alameda County's Davidson courthouse.
The Oakland demonstration followed a raucous but largely peaceful one in San Francisco. Police say officers escorted demonstrators as they marched on the city's Mission District. The group was dispersed by 10 p.m.
The verdict also sparked protests in Los Angeles, where demonstrators gathered in Leimert Park, the city's historically black neighborhood.
Police said that about 200 protesters gathered for what they termed a peaceful vigil.
City News Service said that at one point a smaller group stopped an Expo Line train as police urged them to return to the nearby park. But police couldn't immediately confirm that report.
The protests prompted the Los Angeles Police Department to call for a Citywide Tactical Alert, police officials said, but by about 1 a.m. it was scaled back to a South Bureau Tactical Alert.
There were unconfirmed reports on Twitter that protesters had begun throwing bottles at motorcycle officers, CNS reports.
Lt. Andy Neiman of the LAPD Media Relations Department said another group of 50 to 100 demonstrators started marching around midnight.
"There was a period where crowds were running among vehicles, but police dissuaded them," he said.
Neiman said he knew of no arrests.
Officials said police called in officers from around the city to keep a watch on demonstrators.
More than 40 people gathered at Sacramento City Hall, and the Sacramento Bee reported that protesters chanted: "What do we want? Justice. When do you we want it? Now. For who? Trayvon."A banner behind speakers read, "No justice, no peace!
Martin's killing in February 2012 unleashed debate across the U.S. over racial profiling, self-defense and equal justice. Protesters nationwide lashed out against police in the Orlando suburb of Sanford as it took 44 days for Zimmerman to be arrested. Many, including Martin's parents, said Zimmerman had racially profiled the unarmed black teen. Zimmerman identifies as Hispanic.
Six anonymous female jurors considered nearly three weeks of often wildly conflicting testimony over who was the aggressor on the rainy night the 17-year-old was shot while walking through the gated townhouse community where he was staying and where Zimmerman lived.
Jurors were sequestered during the trial, and they deliberated more than 15 hours over two days before announcing late Saturday night that they had reached a verdict. The court did not release the racial and ethnic makeup of the jury, but the panel appeared to reporters covering selection to be made up of five white women and a sixth who may be Hispanic.
In August 2012, defense attorney Mark O'Mara said Zimmerman and his wife, Shellie, had been living like hermits and weren't working because they feared for their safety.
After Saturday's verdict, police, officials and civil rights leaders urged peace and told protesters not to resort to violence. While defense attorneys said they were thrilled with the outcome, O'Mara suggested Zimmerman's safety would be an ongoing concern.
"There still is a fringe element that wants revenge," O'Mara said. "They won't listen to a verdict of not guilty."
Those watching reacted strongly when the verdict was announced. Martin's mother and father were not in the courtroom when it was read; supporters of his family who had gathered outside yelled "No! No!" upon learning of the verdict.
Andrew Perkins, 55, a black resident of Sanford, angrily asked outside the courthouse: "How the hell did they find him not guilty?"
"He killed somebody and got away with murder," Perkins shouted, so angry he shook, looking toward the courthouse.
Trayvon Martin's brother, Jahvaris Fulton, said on Twitter: "Et tu America?" - a reference to the Latin phrase "Et tu, Brute?" known as an expression of betrayal.
Protesters had taken to the streets late Saturday and into Sunday morning in Florida and other states, largely heeding the advice of officials and others who urged them not to resort to violence.
Authorities said in California media reports that some marchers in Oakland vandalized a police squad car and police formed a line to block some demonstrators there. TV news helicopter footage showed some people trying to start fires in the street and spray painting anti-police graffiti. The demonstration followed a raucous but largely peaceful protest in San Francisco and another in Los Angeles. An Oakland police dispatch said about 100 people protested there but gave no word of any arrests
Celebrities also reacted. Beyonce called at a Nashville concert for a moment of silence for Martin. Rapper Young Jeezy released a song in Martin's memory and Russell Simmons called for peace.
NAACP President Benjamin Todd Jealous started a petition calling for the Justice Department to open a civil rights case against Zimmerman. "The most fundamental of civil rights - the right to life - was violated the night George Zimmerman stalked and then took the life of Trayvon Martin," Jealous wrote in the petition, posted on the website MoveOn.org and addressed to Attorney General Eric Holder.
Martin family attorney Benjamin Crump acknowledged the disappointment of Trayvon Martin's supporters, ranking the teen alongside civil rights heroes Medgar Evers and Emmett Till in the history of the fight for equal justice. However, Crump said, "for Trayvon to rest in peace, we must all be peaceful."
Martin's family maintained the teen was not the aggressor, and prosecutors suggested Martin was scared because he was being followed by a stranger. Defense attorneys, however, said Martin knocked Zimmerman down and was slamming the older man's head against the concrete sidewalk when Zimmerman fired his gun.
Prosecutors called Zimmerman a liar and portrayed him as a "wannabe cop" vigilante who had grown frustrated by break-ins in his neighborhood committed primarily by young black men. Zimmerman assumed Martin was up to no good and took the law into his own hands, prosecutors said.
State Attorney Angela Corey said after the verdict that she believed second-degree murder was the appropriate charge because Zimmerman's mindset "fit the bill of second-degree murder."
"We charged what we believed we could prove," Corey said.
Zimmerman also had some supporters outside the courthouse, including Cindy Lenzen, 50, of Casslebury, and her brother, 52-year-old Chris Bay, who stood watching others chant slogans such as, "the whole system's guilty."
Lenzen and Bay - who are white - called the entire case "a tragedy," especially for Zimmerman.
"It's a tragedy that he's going to suffer for the rest of his life," Bay said. "No one wins either way. This is going to be a recurring nightmare in his mind every night."
Before a special prosecutor assigned to the case ordered Zimmerman's arrest, thousands of protesters had gathered in Sanford, Miami, New York and elsewhere, many wearing hoodies like the one Martin had on the night he died. They also carried Skittles and a can of iced tea, items Martin had in his pocket. President Barack Obama also had weighed in, saying that if he had a son, "he'd look like Trayvon."
Despite the racially charged nature of the case, race was barely mentioned at the trial.
"This case has never been about race or the right to bear arms," Corey said. "We believe this case all along was about boundaries, and George Zimmerman exceeded those boundaries."
One of the few mentions of race came from witness Rachel Jeantel, the Miami teen who was talking to Martin by phone moments before he was shot. She testified that he described being followed by a "creepy-ass cracker" as he walked through the neighborhood.
Jeantel gave some of the trial's most riveting testimony. She said she overheard Martin demand, "What are you following me for?" and then yell, "Get off! Get off!" before his cellphone went dead.
The jurors had to sort out clashing testimony from 56 witnesses in all, including police, neighbors, friends and family members.
