The worst nightmare of any parent is the thought of losing their child. But, for Sybrina Fulton, this wasn’t just a nightmare, it was her reality. In 2012, her unarmed 17-year-old son, Trayvon Martin, was shot and killed by 28-year-old George Zimmerman. Zimmerman wasn’t arrested for the shooting until two entire months later, and he was still acquitted a little over a year later by using Florida’s “Stand Your Ground,” law as his defense.
