JACKSONVILLE, Fla. -- Lucia McBath joined Trayvon Martin's mother Tuesday in Washington, D.C. and spoke out about the "stand your ground" statute to a Senate judiciary committee.
She said "'stand your ground' defies all reason."
She said, "In essence, it allows any armed citizen to self-deputize themselves and establish their own definition of law and order.
Her son, Jordan Davis, 17, was shot and killed last November at a Southside gas station after police say Davis and another man, Michael Dunn, argued over loud music.
Dunn claims he fired his weapon because he feared for his life.
Texas Sen. Ted Cruz, a Republican who believed the law should be decided by the states said, "Self defense is the bedrock of liberty."
The mothers lobbied lawmakers, asking that the 22 states with "stand your ground "statutes revisit the law and clarify it.
They said it's too vague. And while Trayvon Martin's shooter, George Zimmerman, did not use the "stand your ground" defense in his trial, Martin's mother, Sabrina Fulton, said the concept allowed her son's killer to go unpunished.
She said, "The person that shot and killed my son walks the streets today. This law does not work."
McBath worried the same could happen to Dunn.
She said, "Now, I face the real possibility that my son's killer will walk free, hiding behind a statute that lets people claim a threat where there was none."
Michael Dunn is set to go on trial early next year.
