Texas has enacted a law allowing people to use reasonable deadly force to protect themselves and their property. The majority rule has been that if you are attacked, you have a duty to retreat if you can reasonably and safely do so, except if the attack happens in your home- thus the “Castle Doctrine,” because a man’s Home is his Castle. The new law extends the defense to vehicles and workplaces, which practically means that you could drive up next to someone and then shoot them dead, and claim that they threatened to attack you in your car. This seems preposterous, although it is an interesting experiment. If violent crime rates in Texas go down after this law takes effect, I would expect to see similar laws passed in many other states. The arguments as to whether or not it is proper to kill somone who breaks into your house are left as an exercise for the reader.
