Associated Press News Release
The mother of Trayvon Martin will speak at Harvard Law School about changing "stand your ground" self-defense laws.
Sybrina Fulton will be joined by her attorney, Benjamin Crump, at Monday's event.
Fulton's 17-year-old son was shot in central Florida in 2012 by George Zimmerman, who was acquitted of second-degree murder in July.
Since his death, Martin has been speaking out against the controversial law.
Last month, she told a panel of U.S. senators that the laws don't work and must be amended. Democrat have supported Fulton's call. Republicans said it should be left to the states that passed the laws.
According to the National Conference of State Legislatures, at least 22 states have laws that allow that "there is no duty to retreat (from) an attacker in any place in which one is lawfully present."
