California, as well as several other states, have what are referred to as “stand-your-ground-laws.” The purpose of these laws is to allow you to use deadly force when placed in a situation where you need to defend yourself. One of the most famous cases where stand-your-ground laws were a factor in getting someone off a second-degree murder charge was in the Florida trial of George Zimmerman.
If you’re looking through a list of California’s laws you won’t find anything listed as stand your ground laws, what you will find is the Castle Doctrine, which is formally called PC Section 198.5. The strict letter of this particular law enables you to use deadly force whenever you are in your house and are put in a situation where you have “ reasonable fear of imminent peril or great bodily injury.“
The courts will only allow you to use the standing your ground defense during a trial if your case meets a few strict criteria that include:
- The person entered your house unlawfully
- While in your house, the intruder was breaking the law (this effectively prevents you from shooting a police officer while they’re in your home)
- You generally feared for both your safety and the safety of your family
- No one who was lawfully in your home did or said anything that aggravated the intruder, which prompted them to threaten your safety.
It’s worth noting that the intruder doesn’t have to necessarily be inside your home for the Castle Doctrine to be a justifiable defense. There are several instances where justifiable homicide, California Jury Instructions (CALCRIM #505 and #506,) were used in cases where deadly force was used in the defense of someone who used deadly force to defend themselves while at the movies, in parking lots, and a variety of different scenarios.
