In light of George Zimmerman's acquittal on all charges in the shooting death of 17-year-old Trayvon Martin, the Rev. Al Sharpton is calling for protests in 100 cities nationwide, according to Politico. 

The civil rights leader has deemed Saturday "Justice for Trayvon National Day of Action." Sharpton pointed out that had there not been protests back in early 2012 when Martin was killed, Zimmerman wouldn't have been charged. Sharpton hopes the protests on Saturday will have a similar affect and is confident that continued pressure will force a federal civil rights case.

"When they're telling you today, 'I don't know if they're going to get a civil rights trial:' We will. And we will get a civil trial," Sharpton said on the "Tom Joyner Morning Show" on Monday morning. "What we've watched the last several weeks was not the system correcting itself, it was the people correcting the system. Now we've got to finish the job."

Sharpton's National Action Network is organizing the protests at federal court buildings across the country in an attempt to press the Justice Department to bring a civil rights case against George Zimmerman.

Sharpton said his organization plans to maintain the pressure on the Justice Department until a civil rights case is brought, asserting the protests will show that national anger, regarding Zimmerman's exoneration, is not a fleeting display of disapproval.

"It's not over. And we are going to make sure it's not over, that's why we're calling people to ... organize in your city. I don't care if it's 20 people, we want to show the nation that over 100 cities a week later is still demanding justice. We're not having a fit, we're having a movement," Sharpton said.

The event will also usher in a four-week countdown to the 50th anniversary event for the March on Washington on August 24. It will include Martin Luther King III, and Sharpton said it will focus on the Trayvon Martin case and the Voting Rights Act.
