Stevie Wonder has announced that he will no longer perform in states with Stand Your Ground laws. Wonder made the announcement on Sunday in response to a Florida jury’s acquittal of George Zimmerman in the shooting death of Trayvon Martin, saying, “I decided 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.”

While Zimmerman’s legal team never actually invoked Stand Your Ground, the law allows those who reasonably perceive themselves to be in danger of death or great bodily harm to use deadly force to defend themselves, even if it is possible for them to retreat. Right now, there are 22 states that have some form of a Stand Your Ground law.

This is not Wonder’s first foray into political activism. The legendary singer’s music was banned from South African state radio in 1985 after he dedicated an Academy Award to Nelson Mandela, who was jailed by the country’s apartheid regime at the time.
