Laws to Protect You From Home Intruder – CalCrim 506 = “ A Defendant is not required to retreat. He or she is entitled to stand his or her ground and defend his self or herself and, if reasonably necessary, to pursue an assailant until the danger…has passed. This is so even if safety could have been achieved by retreating.” California Penal Code Section 198.5 sets forth that unlawful, forcible entry into one’s residence by someone not a member of the household creates the presumption that the resident held a reasonable fear of imminent peril of death or great bodily injury should he or she use deadly force against the intruder. This would make homicide justifiable.
