Charlene Carruthers coordinates the Black Youth Project, or BYP100, an organization that trains black 18-to-35-year-olds as activists. "We talk about black men, black women, girls and boys, LGBT folks," said Carruthers, who identifies as a black, queer woman and a feminist. "The goal is the liberation of all black people, and for that, we all need to be involved."
For Tuesday, Carruthers planned 28 hours of actions, because "every 28 hours, a police officer or a vigilante kills a black person." More than 400 people were expected at BYP's peaceful protests that start in Chicago at City Hall, and in Washington, from outside the Metropolitan Police Department headquarters.
"Michael Brown could've been my brother. He could've been one of my cousins," Carruthers said.
Carruthers began organizing civil actions at age 18 while studying at Illinois-Wesleyan University. After 10 years mobilizing young people, she said she is confident that young people do the job best. "Every movement that's ever been successful in this world requires young people to be at the forefront. Young people are among the most radical. They have sound powers of analysis, and they are willing to take action.
