Vic Mensa Was On The Front Line Of Chicago Protests Over Police Killing Of Laquan McDonald

'We want justice,' he says.

On Tuesday night, a graphic video that shows a white police officer shooting a 17-year-old black teen to death was released to the public. The shooting took place in October 2014, but the officer, Jason Van Dyke, was not charged with first degree murder for the death of Laquan McDonald -- who was shot 16 times in the incident -- until last night, shortly before the public release of the video.

In the aftermath, large crowds joined in protest on the streets of Chicago. Among the many concerned citizens was Vic Mensa.

In a video captured by CBS News, the rapper can be seen clashing with police.

Another video shows a fellow protestor asking the Chicago native why he decided to come out and rally.

"I just got hands put on me by police," he says. "We want justice for Laquan and we want justice for our people."

According to reports, protests lasted until about 1:30 a.m. local time, as they chanted phrases like "16 shots," as well as "We gon' be alright," the refrain from Kendrick Lamar's single "Alright."

"Many in the community feel betrayed," Rev. Ira Acree told reporters after a meeting earlier in the day with the city's mayor, Rahm Emmanuel.

Vic's friend and frequent collaborator, fellow Chicago native Chance The Rapper, was out of town, but expressed his support online.

This isn't the first time Vic has taken a stand in public. Just a few months ago, at the VMAs, the 22-year-old showed up in an outfit that called out police brutality, with the front of his shirt emblazoned with the face of exiled activist Assata Shakur.

“She’s still the FBI’s Most Wanted Woman in 2014 after being locked up as a political prisoner in 1977,” he told to MTV News at the time. “That’s ridiculous to me.”
