TALLAHASSEE (CBSMiami/NSF) – The mother of Trayvon Martin will be at Florida’s Capitol this week to support legislation that would repeal the state’s “stand your ground” self defense law.

Sen. Dwight Bullard, D-Miami, and Rep. Alan Williams, D-Tallahassee are sponsoring the repeal bill (HB 4009). The state’s self defense law contains an element known as the Stand Your Ground provision which allows people who feel threatened to shoot back at assailants out in public.
