PHILADELPHIA (CBS) — The fatal shooting of a black man involving two white police officers in Baton Rouge, Louisiana has sparked outrage and is drawing national attention. Protests were being held in several cities across the country, including in Philadelphia.

Dozens of protestors marched up and down the streets of Center City on Wednesday, chanting “no justice, no peace” — taking a stand against police brutality in the wake of Alton Sterling’s death.

“It’s just enough. This is enough. What do we do at this point now? They’re killing us,” said Rennie Robinson. “They’re out here actually killing us.”

Robinson says she’s tired of seeing people die at the hands of police and she wants to raise awareness about it.

“I’m not saying that all cops are bad, and I hear it all the time ‘there are just a small few cops,'” she said. “Well, why don’t those cops come out? Why don’t they stand up for what they are doing? That is their job and they’re not protecting us. They’re not protecting us.”

“I want to stand in solidarity with those in Louisiana, Baton Rouge who are suffering today from the murder of Alton Sterling,” said Reverend Nicolas O’Rourke.

He called it his duty to speak for those who do not have a voice.

“We have a tendency to turn our eyes and be desensitized to the issues going on,” he said. “As a result, we use traditional practices of coming out standing in solidarity, lifting our voices, putting our feet to the pavement to actually make sure that it’s clear that people of color are enraged and they are not standing for it any longer.”

Philadelphia police were on hand to monitor the protest and shut down roadways in Center City as demonstrators made their way through the streets.

Around a dozen people were arrested.
