Thousands of people marched in Minneapolis Saturday to protest the fatal shooting of a woman by a federal immigration officer there and the shooting of two people in Portland, Oregon, as Minnesota leaders urged demonstrators to remain peaceful.

The Minneapolis gathering was one of hundreds of protests planned in towns and cities across the country over the weekend. It came in a city on edge since the killing of Renee Good on Wednesday by an Immigration and Customs Enforcement officer.

“We’re all living in fear right now,” said Meghan Moore, a mother of two from Minneapolis who joined the protest Saturday. “ICE is creating an environment where nobody feels safe and that’s unacceptable.”

On Friday night, a protest outside a Minneapolis hotel that attracted about 1,000 people turned violent as demonstrators threw ice, snow and rocks at officers, Minneapolis Police Chief Brian O’Hara said Saturday. One officer suffered minor injuries after being struck with a piece of ice, O’Hara said. Twenty-nine people were cited and released, he said.

Minneapolis Mayor Jacob Frey stressed that while most protests have been peaceful, those who cause damage to property or put others in danger will be arrested. He faulted “agitators that are trying to rile up large crowds.”

“This is what Donald Trump wants,” Frey said of the president who has demanded massive immigration enforcement efforts in several U.S. cities. “He wants us to take the bait.”

Minnesota Gov. Tim Walz echoed the call for peace.

“Trump sent thousands of armed federal officers into our state, and it took just one day for them to kill someone,” Walz posted on social media. “Now he wants nothing more than to see chaos distract from that horrific action. Don’t give him what he wants.”

Communities unite in frustration

The U.S. Department of Homeland Security says its deployment of immigration officers in the Twin Cities is its biggest ever immigration enforcement operation. Trump’s administration has said both shootings were acts of self-defense against drivers who “weaponized” their vehicles to attack officers.

Connor Maloney said he was attending the Minneapolis protest to support his community and because he’s frustrated with the immigration crackdown.
