Onstage Sunday night in Quebec City, in the wake of George Zimmerman’s acquittal in the death of Trayvon Martin, Stevie Wonder made an announcement. “I decided today that until the Stand Your Ground law is abolished in Florida, I will never perform there again. As a matter of fact, wherever I find that law exists, I will not perform in that state or in that part of the world. … You can’t just talk about it, you gotta be about it.â€
