George Zimmerman's arrest shows the "stand your ground" law doesn't exempt people from prosecution, says Gabriel Chin.
-- Many people consider Trayvon Martin to be a 21st century Emmett Till.
George Zimmerman killed Trayvon Martin as the 17-year-old African-American returned home after buying Skittles and iced tea.
After weeks of suspense, Florida special prosecutor Angela Corey has ordered Zimmerman arrested and charged him with second-degree murder.
Florida's "stand your ground" law protects, some say over-protects, the right of self-defense.
But judges and juries still have the power to evaluate the truth of self-defense claims, and defendants will be convicted of homicide if the prosecution can prove that killings were outside the law.
