Trayvon Martin was senselessly murdered this year, a victim of gun violence and the widely criticized “Stand Your Ground” legislation that likely emboldened the teenager’s killer. In the wake of the tragedy, the tide is turning. Elected officials across the country are increasingly speaking out against Florida-style “Shoot First” laws, and many original supporters of the legislation are recanting their previous support.

This Father’s Day, join Trayvon Martin’s father, Tracy Martin, and add your name to this national petition demanding that all “Stand Your Ground” laws be repealed.
