CHARLOTTESVILLE, Va. -- The city of Charlottesville marked the anniversary of last summer's white supremacist violence that sent ripples through the country with largely peaceful vigils and other events, but police had a brief, tense confrontation with demonstrators angry over the heavy security presence there this weekend.
"Why are you in riot gear? We don't see no riot here," activists chanted Saturday evening.
Shortly before a planned evening rally to mark the anniversary of a campus confrontation between torch-carrying white nationalists and counterprotesters, activists unfurled a banner that said, "Last year they came w/ torches. This year they come w/ badges."
A group of more than 200 protesters - students, residents and others - then marched to another part of the University of Virginia's campus, where many in the crowd shouted at officers in riot gear forming a line.
At one point, UVA Medical Center went on lockdown, with employees receiving an alert to stay indoors due to the protesters moving in "unpredictable directions," CBS Charlottesville affiliate WCAV reports.
Kibiriti Majuto, a coordinator for UVA Students United, said the students moved to another part of campus because they didn't want to be "caged" in the area where the planned rally area. Majuto said police "were not on our side" last year when white supremacists surrounded counterprotesters on the rotunda.
"Cops and Klan go hand in hand," he said.
Charlottesville city councilman Wes Bellamy said he tried to diffuse the situation and told the police commander that students were upset by the officers' tactics, with "over-the-top" riot gear
After a few minutes, most demonstrators began walking away. There were no immediate reports of arrests on campus.
At some point after the UVA rally, dozens of demonstrators marched off campus through other parts of the city, chanting "Whose streets? Our streets" and "Who do you protect? Who do you serve?"
The group made its way to downtown before dispersing.
The rest of the day had been much quieter.
In the downtown shopping district Saturday morning, officers outnumbered visitors. Concrete barriers and metal fences had been erected, and police searched bags at two checkpoints.
"It's nice that they're here to protect us," said Lara Mitchell, 66, who works at a shop selling artwork, jewelry, and other items. "It feels good that they're here in front of our store. Last year was a whole different story. It looked like a war zone last year."
On Aug. 12, hundreds of white nationalists - including neo-Nazis, skinheads and Ku Klux Klan members - descended on Charlottesville in part to protest the city's decision to remove a monument to Confederate Gen. Robert E. Lee from a park.
Fighting broke out between attendees and counterprotesters that day. Authorities eventually forced the crowd to disperse, but a car later barreled into a crowd of peaceful counterprotesters, killing 32-year-old Heather Heyer.
The death toll rose to three when a state police helicopter that had been monitoring the event and assisting with the governor's motorcade crashed, killing two troopers.
The organizers of that rally planned to march in Washington, D.C. on Aug. 12, 2018. Heyer's mother, Susan Bro, told CBS News' DeMarco Morgan on Saturday that she didn't want people to "respond with violence" on the anniversary of her daughter's death. There's "no place for hate," she said.
On Saturday, remembrance events included a "morning of reflection and renewal" at UVA with music, poetry and an address from University President James Ryan.
Ryan recalled how a group of students and community members faced off against the white supremacist marchers near a statue of Thomas Jefferson on campus, calling it a "remarkable moment of courage and bravery."
Clara Carlson was one of those counterprotesters. Carlson, 22, said she feared for her life when she and a group of her friends were surrounded by the phalanx of young white men at the statue, and she added that police didn't intervene to help her or her friends. This year, she said the university is afraid of students demanding change, and she blasted the police presence as heavy-handed.
"They sent police in riot gear," she said, standing on campus. "These state troopers are staying in these very student dorms right here."
Lisa Woolfork, a University of Virginia professor and Black Lives Matter Charlottesville organizer, said police mounted a "huge, overwhelming show of force to compensate for last year's inaction."
"Last year, I was afraid of the Nazis. This year, I'm afraid of the police," Woolfork said
An independent investigation of the rally violence, led by a former federal prosecutor, found the chaos last year stemmed from a passive response by law enforcement and poor preparation and coordination between state and city police.
But Saturday's security measures comforted some, such as Kyle Rodland, who took his young sons to get ice cream downtown. He said he felt much safer than last year, when he left town with his family and stayed with his parents after seeing people armed with long rifles walking around.
Heyer's mother, Susan Bro, told The Associated Press on Saturday that she has been dreading the anniversary of her daughter's death for months.
Bro likened losing a child to standing in shallow water as waves roll continually in.
"You let the wave wash over, and you don't chase it. You let it go and you're OK until the next one comes," she said. "But today, I feel like high tide is in."
On Sunday, further events marking the anniversary were expected in Charlottesville and Washington, where Jason Kessler, the primary organizer of last summer's rally, has obtained a permit for a "white civil rights" rally.
