Thousands of demonstrators rallied nationwide on Saturday one week after the acquittal of George Zimmerman in the shooting death of unarmed African-American teenager Trayvon Martin. In New York City, Trayvon Martin’s mother, Sybrina Fulton, addressed a rally of hundreds of people in front of police headquarters.

Sybrina Fulton: “As I sat in the courtroom, it made me think that they were talking about another man. And it wasn’t. It was a child, who thought as a child, who acted as a child, who behaved as a child. And don’t take my word for it. He had a drink and candy. So, not only — not only do I vow to you to do what I can for Trayvon Martin, I promise you I’m going to work hard for your children, as well, because it’s important.”

Fulton was joined by speakers including the Reverend Al Sharpton. The musicians Jay Z and Beyoncé were among those in attendance, drawing calls from the crowd of “Boycott Florida” after Stevie Wonder’s announcement last week. Wonder said he would not perform in any state with “Stand Your Ground” laws in effect. The “Justice for Trayvon” rallies were held in dozens of other cities including Miami, Orlando, Chicago, Los Angeles, San Francisco, Oakland and Atlanta.
