MILWAUKEE — The family of a black man shot 14 times by a white police officer in a Milwaukee park marks the spot where he died with red spray paint before starting a rally through city streets.

“Shame on you. People of color are people, too,” protesters chant while carrying signs declaring, “Black Lives Matter.”

The rallies are one way Dontre Hamilton’s family has kept his name in the news in the six months since his death. Smaller and more orderly than those in Ferguson, Mo., the protests have not drawn national attention but have produced results. The man who shot Hamilton was fired, the first Milwaukee officer in decades to face such discipline in a fatal on-duty shooting.

Now the family wants more: criminal charges for the officer, and improvements in the way mentally ill people — Hamilton had schizophrenia — are treated by police.

“They messed with the wrong family. ... I’m not going to back down,” said Nate Hamilton, Dontre Hamilton’s brother.

Hamilton’s family participated in a vigil days after his April 30 death but then said little publicly as they waited out an investigation into the shooting. They wanted details about what happened and the officer disciplined. They were frustrated months later, when protests erupted in Ferguson following the shooting of a black 18-year-old, Michael Brown, by a white officer.

“We tried to be accepting and respectful of the way the system works. ... Until it got to the point where the Mike Brown thing happened,” Nate Hamilton said. “Now, you know who this police officer is, you’re seeing them get information, and in Milwaukee, we’re not getting no information.”

The family joined a Milwaukee demonstration to support those in Ferguson, and attention focused on the similarities between the two cases.

Overall, the protests have been peaceful, which Nate Hamilton said is crucial to building support for the family’s goals. Police Chief Edward Flynn promised more training for officers dealing with people with mental illness and, on Oct. 15, fired Officer Christopher Manney for instigating the fight that led to the shooting.

Hamilton’s family wants to see Manney charged. The district attorney’s office has delayed a decision until it gets a recommendation from a use-of-force expert.
