All eyes were on Minneapolis on Monday as the trial of Derek Chauvin, the former police officer charged with murder and manslaughter in the death of George Floyd, entered a key phase of the proceedings.

Inside the Hennepin County Government Center, the prosecution and defense made their opening arguments and began the process of questioning witnesses inside the 18th-floor courtroom.

Outside the high-rise building, city officials have taken measures to guard the area against any potential unrest that could arise during the high-profile trial. Metal fencing and concrete barriers were installed around the courthouse and National Guard troops are stationed outside.

Roughly a dozen protesters attempted to block traffic in the nearby streets as the trial unfolded Monday. 

Here are some of the most compelling photos from outside the courthouse:

“It’s a lot,” said one protester who identified himself only as Joe, describing the “high emotions” at play. “I’m hoping, I mean, realistically I doubt that Derek Chauvin’s gonna get convicted. But I hope that he actually does get convicted.”

Grunt Mezera of Minneapolis has been regularly participating in protests against racial injustice since uprisings began over George Floyd’s death in 2020. “It was said today, and it really hit me home, whiteness is on trial today,” said Mezera. “And the world that we live in where we believe whiteness is the norm, the right, the way it should be, is on trial. Because whiteness got us here.”

Carolyn Ruff, co-founder of Black Lives Matter Women of Faith in Chicago, joined the protesters in the street. “If he’s not convicted, I feel sorry for America,” Ruff told HuffPost of Chauvin. “We want a conviction. He killed a human being. It’s only right that he be convicted. He’s not above the law,” she said. Ruff, who also protested the fatal shooting of Laquan McDonald by Chicago Police Officer Jason Van Dyke, said “it really meant a lot” to be in Minneapolis for opening arguments in Chauvin’s trial. She said she’s likely to return to the city for what she hopes will be Chauvin’s conviction.
