COLLEGE STATION, Texas -- The shooting death of Trayon Martin in Florida brought the stand your ground law to the forefront of American's minds.
Shortly after that shooting, researchers at Texas A&M started looking into state's with those laws and found the laws may not actually deter crime. Using FBI crime stats, justifiable homicides nearly doubled between 2000 and 2010.
Texas passed the Castle Doctrine law in 2007. The study's researcher suggest the laws don't seem to deter crime and possibly increase murder and manslaughter cases.
In the Texas version of the law, if you are in fear and have the legal right to be where you are, you don't have to retreat, you can defend yourself. If you kill someone in self-defense, you are granted immunity in civil lawsuits.
