Protests erupt from Boston to California as Confederate monument tensions boil over In addition to Boston, protests sprang up in US cities like Atlanta and Dallas.

 -- The weekend after a white nationalist rally collapsed into chaos in Charlottesville, Virginia, leading to the alleged murder of an anti-racism activist, protests erupted across the country against white supremacy, racism and the presence of confederate monuments.

Boston

Tens of thousands counterprotesting a rally purporting to be about free speech swarmed Boston on Saturday, leading to a few conflicts with police and widespread attention from traditional and social media.

A total of 33 arrests were made Saturday in Boston, primarily resulting from disorderly conduct and from alleged assaults against police officers, the Boston Police Department said. Police indicated that some demonstrators were throwing rocks and bottles of urine, but that did not represent the majority of participants, according to Police Commissioner William Evans.

"99.9 percent of the people here were for the right reasons" and participated peacefully, Evans said.

Dallas

Thousands of demonstrators gathered around the area of Dallas City Hall Saturday at a rally calling for unity, according to ABC affiliate WFAA.

Over a dozen activists, politicians and faith leaders spoke prior to a candlelight vigil, the affiliate reported.

Tensions were high near Confederate War Memorial Park, where calls have been growing to remove statues commemorating civil war veterans who fought for the Confederacy, WFAA reports.

Monuments commemorating the confederacy on public land "must be and will be removed," Dallas Mayor Dwaine Caraway said at a Friday press conference, which featured black members of Dallas's city council, according to the Dallas Morning News.

Kevin Felder, one of the city council members, said that, "Taxpayer dollars should not support vestiges of racism and white supremacy," in reference to the statues, while speaking at Friday's press conference.

Five people were detained during Saturday’s rally and then released without charges, the Dallas Police Department told ABC News.

Memphis

Six demonstrators were arrested in Memphis following a rally to remove a monument to Nathan Bedford Forrest, a slavetrader and lieutenant general who served in the Confederate Army during the Civil War, according to ABC affiliate WATN.

The monument has become a flashpoint of tension between anti-racism activists, who covered it with anti-racist signs on Saturday, and those who seek to protect the history of the Confederacy.

Gene Andrews, a caretaker for Nathan Bedford Forrest's boyhood home, and a participant in the white nationalist rally that took place in Charlottesville last week, told the Tennessean newspaper that tensions over the monuments were building.

"I think people have had enough," Andrews told the paper. "Somewhere there’s going to be a line drawn, and if it’s a war that’s coming so be it."

Atlanta

Hundreds of groups gathered in Centennial Olympic Park on Saturday in Atlanta to march against racism and hate, according to ABC affiliate WSB.

The march ended at the tomb of Dr. Martin Luther King Jr., the affiliate reported.

Indianapolis

Anthony Ventura, a 30-year-old man, was arrested after police say he damaged the Confederate statue with a hammer, according to ABC affiliate WRTV.

Laguna Beach, California

In Laguna Beach on Saturday a group of about 300 demonstrators met for a preemptive response to a far-right rally planned for today, the LA Times reports. At the “America First!” rally, set for 6:30 p.m., participants plan to call attention to victims of crimes committed by immigrants living in the U.S. illegally.

Saturday’s gathering of counterprotesters, set up to show solidarity and strength, was officially called “From Charlottesville to Laguna Beach: We Stand Together.” Laguna Beach Mayor Toni Iseman helped organize the event and spoke to the crowd on Saturday, the LA Times reports.
