On Tuesday there were protests in a number of U.S. cities, marking one year since the killing of Trayvon Martin, a 17 year-old African-American, in Sanford, Florida.
The Stop Mass Incarceration Network, which originally criticized the quick release of George Zimmerman after Martin's death last year, issued a call to protest on the one year anniversary, stating: "Trayvon's parents heroically stood up and called for justice for Trayvon, and in response people poured into the streets all across the country. This is the only reason Zimmerman was re-arrested and charged for his crime."
