About 200 people rallied in downtown Madison on Sunday, calling for equal justice after a not guilty verdict in the Trayvon Martin case.
The rally outside the state Capitol was without violence, mirroring protests that have erupted throughout the country.
A jury in Sanford, Fla., found George Zimmerman, a neighborhood watch volunteer, not guilty in the death of Martin.
I was incredibly angry and hurt," said Alix Shabazz of Madison, who attended the rally. "A lot of people are angry. Now it's about taking that anger and using it for positive action."
One speaker at the rally urged people to stand up to racism in the classroom and at work.
President Barack Obama called for the protests to remain peaceful. The U.S. Justice Department said it was looking into whether prosecutors should file criminal civil rights charges against Zimmerman, now that his state case is over.
A long list of people spoke at the Madison rally, mostly upset with the verdict and asking for change.
"I'm sick of living in a society where it's open season on blacks," said one man. "I think a lot of other people are too, and that's why we're here, to do something about it."
Meanwhile, Milwaukee police said they responded to two separate protests Saturday. One group of about 40 demonstrators dispersed after about a half hour with no arrests. Another group of up to 75 people gathered around midnight in Milwaukee.
One person in that group was arrested for resisting and obstructing an officer.
Other protests happened nationwide Sunday, a day after a jury found the former neighborhood watch volunteer not guilty. The case unleashed debate over racial profiling, self-defense, and equal justice.
George Zimmerman's lawyer said he hopes people can allow his client to live his life without feeling threatened.
He said prosecutors never could have proved the murder charge and wouldn't have even taken the case to court if Zimmerman was black.
