Sybrina Fulton, the mother of Trayvon Martin, the unarmed black Florida teenager killed in 2012 by George Zimmerman, is taking her fight in her son's memory to a Senate panel on Tuesday, demanding that states clarify their "Stand your ground" laws in self-defense cases, according to the Associated Press. 

The laws are known for excusing a refusal to retreat in the face of extreme danger, allowing people to defend themselves without fear of prosecution once they adequately prove their case. However, since Trayvon's shooting and George Zimmerman's acquittal, Fulton says, the laws can be "confusing and applied inconsistently," the AP reports.

"By being unclear in when and how it is applied, 'Stand your ground' in its current form is far too open to abuse," Fulton said in prepared testimony for the Senate Judiciary Committee, according to the AP.
