DENVER – High school and college students across the country continue to protest grand jury decisions in the cases of Michael Brown and Eric Garner, though many are unsure exactly what they’re protesting.

Denver student protest

Students from four Denver area high schools walked out of class for a second day Thursday and blocked traffic and shouted profanities as they marched to Colorado’s Capitol building while police escorted the teens. The students carried banners reading “We are Ferguson” and others, sounded blow horns, and chanted slogans like “F*ck the police!” ABC reports.

Students from Abraham Lincoln, Montbello, and George Washington high schools, as well as students from Bruce Randolph Middle School took part in the protest. The protests erupted after a grand jury in New York declined to indict a New York City police officer who put Garner in a choke hold that caused his death. It was the second massive student protest since the Ferguson grand jury opted not to indict an officer who shot and killed Michael Brown, according to the news site.

During the previous protest four bicycle officers escorting the students was hit and injured by a car, after which students chanted “Hit him again!”

“Many of the students we interviewed today and yesterday … had trouble articulating the reason they were protesting in the first place,” ABC reporter Russell Haythorn said.

“Police just shot him because he was black, or something like that,” one student said.

“They are just using their power and authority over us,” said another.

In Palo Alto, California, dozens of protestors marched onto Highway 101 Wednesday, and briefly blocked traffic before police arrived and cleared the roadway. That protest, organized by Stanford University students, coincided with a “die-in” protest at Powell and Market Streets in San Francisco, where student blocked traffic for more than an hour, ABC reports.

In Oakland, students chanting “Justice for Eric Garner” took over the corner of 14th Street and Broadway around 5 p.m., according to the news site.

The Oakland protestors were met by police officers in riot gear as they marched down Broadway on their way to police headquarters. The protestors then dispersed into smaller groups before gathering again in the Piedmont business district.

“We got a lot of issues we need to handle. They’re killing us and it’s not just black people it’s all people of color,” Satima Flaherty, 27, told the crowd in Oakland, according to ABC. “They’re killing us back to back and they’re laughing at us – it’s a mockery.”

“Oakland police made a total of 169 arrests as freeways were blocked, fires were set, windows were broken and business were looted,” ABC reports.

University at Albany students held a more peaceful protest on campus Wednesday, where they also blocked traffic on four-lane Washington Avenue.

“UAlbany Deputy Chief of Police Aran Mull, who joined the protest in exchange for students moving off the street, said students ‘absolutely got heard’ at the afternoon gathering,” the Albany Times Union reports. “No students were arrested or ticketed during the peaceful protest.”

Princeton “die-in”

In Charlottesville, Virginia, University of Virginia students held an on-campus portest of the Eric Garner grand jury decision, chanting “Black lives matter!” and toting posters that read “Wake up!” and “Amadou Diallo, Sean Bell, Oscar Grant, Eric Gardner, Mike Brown, Tamir Rice” – names of black men who have been killed by police since 1999, according to NewsPlex.com.

That protest, as well as one held at Temple University, were largely peaceful, as well.

The Temple University “die-in” protest included about 200 people who reportedly fell to the ground in unison to simulate death, CBS reports.

“People aren’t going to be quiet anymore. This is a different era,” Temple student Michael Larmond told the news site.

Thursday afternoon at the University of Texas, dozens of protesters laid down in the street for their own “die-in” while others knelt beside them holding signs like “We have the right to film.”

“At 12:30 p.m., when the UT Tower bell rang, protesters rose up and chanted, ‘No justice, no peace, black lives matter,’” according to the Statesman.

Princeton University students also held a 45-minute “die-in,” NJ.com reports.

“When the clock struck 11:30 a.m., hundreds of students poured out of halls on campus with their hands raised. The chants included ‘No justice, no peace!’ ‘Hands up, don’t shoot!’ and ‘We can’t breathe!’” according to the news site.
