A Texas lawmaker plans to introduce legislation to amend the state’s self-defense “Castle Doctrine” law in the wake of the Trayvon Martin shooting in Florida, according to a report by KHOU-TV in Houston.

Democratic state Rep. Garnet Coleman told the station the Texas legislature went too far in 2007 when it removed the “duty to retreat before using deadly force” clause from the law, which gives citizens a green light to defend themselves, or stand their ground, rather than run from a confrontation. He said the change in wording had a disproportionate impact on minorities.

“The reality is . . . that it’s all about the perception whether someone is or isn’t going to use deadly force, which allows someone to shoot first and ask questions later,” Coleman said. “That turns into an affirmative defense against prosecution.”
