WASHINGTON – Thousands of protesters marched across the country Saturday -- past the White House in the nation's capital, along iconic Fifth Avenue in New York and in front of Boston's Statehouse -- to call attention to the deaths of unarmed black men at the hands of police and urge lawmakers to take action.
Chanting "I can't breathe!" "Hands up, don't shoot!" and waving signs reading "Black lives matter!" the demonstrators also staged "die-ins" as they lay down across intersections and in one city briefly scuffled with police blocking an onramp to an Interstate.
"My husband was a quiet man, but he's making a lot of noise right now," said Washington protest marcher Esaw Garner, widow of Eric Garner, 43, who died in July after being put in a chokehold by New York City police during an arrest for allegedly selling loose, untaxed cigarettes.
"His voice will be heard. I have five children in this world and we are fighting not just for him but for everybody's future, for everybody's past, for everybody's present, and we need to make it strong."
Organizers had predicted 5,000 people at the Washington march, but the crowd appeared to far outnumber that. They later said they believed as many as 25,000 had shown up. It was not possible to verify the numbers; Washington police do not release crowd estimates.
Garner's mother, Gwen Carr, called the demonstrations a "history-making moment."
"It's just so overwhelming to see all who have come to stand with us today," she said. "I mean, look at the masses. Black, white, all races, all religions. ... We need to stand like this at all times."
Joining the Garners in Washington were speakers from the family of Tamir Rice, a 12-year-old killed in Ohio as he played with a pellet gun in a park, and the Rev. Al Sharpton, who helped organize the marches.
"Members of Congress, beware we're serious ...," Sharpton said. "When you get a ring-ding on Christmas, it might not be Santa; it may be Rev. Al coming to your house."
Several speakers asked the crowd to chant, "I can't breathe." Garner, 43, had gasped those words before his death. Some protesters also wore those words on shirts. Other speakers called for a chant of "Hands up, don't shoot," and protesters also waved signs reading "Black Lives Matter!"
Just before the crowd marched to the Capitol, the rallying was interrupted briefly by more than a dozen protesters who took the stage with a bullhorn. They announced that they were from the St. Louis area and demanded to speak.
"This movement was started by the young people," said Johnetta Elzie, who ultimately was allowed by rally organizers to speak.

Organizers called the interruption unnecessarily divisive. But some in the Missouri group, mostly in their 20s, said they were disappointed and found the rally staid and ineffective.
"I thought there was going to be actions, not a show. This is a show," Elzie said.
Protests -- some violent -- have occurred around the nation since grand juries last month declined to indict the officers involved in the deaths of Brown and Garner. Before the crowd started marching, Sharpton directed, "Don't let no provocateurs get you out of line. ... We are not here to play big shot. We are here to win."
Washington, D.C., and U.S. Park Police said they had made no arrests in the capital protests. In Boston, however, about two dozen people were arrested for disorderly conduct after scuffling with officers blocking an Interstate 93 onramp near the Nashua Street Jail.
The noisy march through the heart of Manhattan swelled to at least 25,000 people, police said. It snarled traffic but remained peaceful, with no arrests reported by late afternoon.
Among the large crowds were family members of people killed by New York City police going back decades.
Donna Carter, 54, marched with her boyfriend, whose teenage son was shot and killed by police in the 1990s while carrying a toy gun.
"It's good to see people of all colors here to say enough is enough," said Carter, who's black. "I'm a parent and every child that's killed feels like my child."
Others were there to show their outrage, including Rich Alexandro, 47, who carried a handmade sign with dozens of names of victims of police killings in which officers were never charged.
"It just seems like the cops are Teflon," Alexandro said. "There's no justice."
On the eve of Saturday's nationwide protests, demonstrators in Nashville, Tennessee, staged "die-ins" in the country music capital's honky-tonk district and another in The Gulch, home to new upscale condominiums and restaurants, The Tennessean reported.
The Friday night protest started with a candlelight vigil outside the Metro Nashville Police Department, growing to about 150 people as it moved to Lower Broadway, where the "Black Lives Matter" chant mixed with the music spilling out of the honky-tonks. Tourists on the sidewalks snapped photos as the demonstrators lay down in the street.
Politicians and others have talked about the need for better police training, body cameras and changes in the grand jury process to restore faith in the legal system.
Terry Baisden, 52, of Baltimore said she is "hopeful change is coming" and that the movement is not part of a fleeting flash of anger.
She said she hasn't protested before but felt compelled to because "changes in action, changes in belief, happen in numbers."
Sheryce Holloway, a recent graduate from Virginia Commonwealth University in Richmond, attended a smaller gathering outside Robert F. Kennedy Stadium in Washington ahead of the main rally. She said she also has been participating in protests at her alma mater.
Holloway said the goal of the protests is "ending blue-on-black crime."
"Black lives do matter."
D.C. Police Chief Cathy Lanier said the Washington march was peaceful. She mingled with the crowd and said she wanted to show solidarity with the marchers.
"This is one of the most well-organized events I've seen," Lanier said.
