The father of the slain black teenager Trayvon Martin has issued a Father’s Day appeal for a nationwide review of “Stand Your Ground,” the purported “self-defense” law that critics say enabled his son’s murder. In a video circulated on the internet, Tracy Martin urged supporters to pressure their local governor on similar laws in their state.

Tracy Martin: “This Father’s Day will be the first without my son, Trayvon. I’ll say a prayer for all the dads across America who share this grief with me. Last year, 30,000 fathers lost a son or a daughter from senseless gun violence. Dads, we have to come together to protect our children. I’m asking you to consider sharing this message with the governor of your state that has a similar Stand Your Ground law. Ask them to review these dangerous laws. If we do, next year thousands more dads will have a happy Father’s Day.”

Trayvon Martin’s mother, Sybrina Fulton, issued a similar Mother’s Day appeal last month.
