NEW YORK —
"I'm sure jurors did what they felt was right in accordance with the law but maybe the law is wrong, maybe society is wrong; there's a lot that needs fixing," she said.
At a youth service in Sanford, Fla., where the trial was held, teens wearing shirts displaying Martin's picture wiped away tears during a sermon at the St. Paul Missionary Baptist Church.
Protesters also gathered in Atlanta, Miami, Milwaukee, Philadelphia, and Washington, D.C., along with a host of other cities.
In Miami, more than 200 people gathered for a vigil. "You can't justify murder," read one poster. Another read "Don't worry about more riots. Worry about more Zimmermans."
Carol Reitner, 76, of Miami, said she heard about the vigil through an announcement at her church Sunday morning. "I was really devastated. It's really hard to believe that someone can take the life of someone else and walk out of court free," she said.
In Philadelphia, about 700 protesters marched from LOVE Park to the Liberty Bell, alternating between chanting Trayvon Martin's name and "No justice, no peace!"
"We hope this will begin a movement to end discrimination against young black men," said Johnathan Cooper, one of the protest's organizers. "And also to empower black people and get them involved in the system."
In Atlanta, a crowd of about 75 protesters chanted and carried signs near Centennial Olympic Park.
"I came out today because a great deal of injustice has been done and I'm very disappointed at our justice system; I'm just disappointed in America," said Tabatha Holley, 19, of Atlanta.
Civil rights leaders, including the Revs. Jesse Jackson and Al Sharpton, urged peace in the wake of the verdict. Jackson said the legal system "failed justice," but violence isn't the answer.
But not all the protesters heeded those calls immediately after the verdict.
In Oakland, Calif., during protests that began late Saturday night, some angry demonstrators broke windows, burned U.S. flags and started street fires. Some marchers also vandalized a police squad car and used spray paint to scrawl anti-police graffiti on roads and Alameda County's Davidson courthouse.
