Last Friday, white police officer Matt Kenny shot and killed 19-year-old Tony Robinson after being assaulted by him. The incident started as Kenny responded to a call regarding a man getting in the way of traffic.
Hundreds of demonstrators, many of them high school students, filled the Wisconsin state capitol building, according to CBS News. The protesters chanted "Stand up, fight back, no more black men under attack" and "indict, convict, send those killer cops to jail — the whole damn system is guilty as hell."
Turin Carter, an uncle of the deceased, called Monday for continued protests.
"I encourage everybody to show support regardless of race because this is truly a universal issue…. We don't want to stop at just 'black lives matter,' because all lives matter," Carter told reporters as quoted by CNN.
The United States has seen waves of mass protest against police brutality and racism in 2014, after African-American Eric Garner died in an illegal chokehold administered by a white police officer in New York City, and another white officer killed Michael Brown, an unarmed black teen, in Ferguson, Missouri. Neither officer was indicted.
