Trayvon Martin’s mother, Sybrina Fulton, issued a Mother’s Day appeal this weekend for a nationwide review of “Stand Your Ground,” the purported “self-defense” law that critics say enabled the killing of her son.

Sybrina Fulton: “Just like me, 30,000 mothers lost their children this year to senseless gun violence. Nobody can bring our children back. But it would bring us comfort if we can help spare other mothers the pain that we will feel on Mother’s Day and every day for the rest of our lives. I’m asking you to join Florida by calling upon the governor of your state to reexamine similar 'stand your ground' laws throughout the nation to keep our families safe.”

Since losing her son, Fulton has tirelessly campaigned for justice in his case and for the tightening of gun control laws in the United States. It was revealed this weekend that a large number of Fulton’s colleagues at Miami-Dade County have collectively donated their vacation days to give Fulton eight months of paid vacation, worth over $40,000 in days off of work.
