Pennsylvania On Tuesday, June 28, 2011, Pennsylvania (PA) Governor Tom Corbitt (R) signed a bill extending that state's traditional castle doctrine protections to assaults outside the home. The new legislation passed both houses with overwhelming support and expands the state’s castle doctrine and stand-your-ground protections to allow the right to use a gun or other deadly force in self-defense in situations outside a person’s home or business.[30] It applies when "deadly force is immediately necessary to protect [...] against death, serious bodily injury, kidnapping or sexual intercourse compelled by force or threat".[31]
It explicitly denies a duty to retreat and provides legislative protection from civil actions resulting from the use of deadly force in acts of self-defense. The PA General Assembly found that:
(1) It is proper for law-abiding people to protect themselves, their families and others from intruders and attackers without fear of prosecution or civil action for acting in defense of themselves and others.
(2) The Castle Doctrine is a common law doctrine of ancient origins which declares that a home is a person's castle.
(3) Section 21 of Article I of the Constitution of Pennsylvania guarantees that the "right of the citizens to bear arms in defense of themselves and the State shall not be questioned."
(4) Persons residing in or visiting this Commonwealth have a right to expect to remain unmolested within their homes or vehicles.
(5) No person should be required to surrender his or her personal safety to a criminal, nor should a person be required to needlessly retreat in the face of intrusion or attack outside the person's home or vehicle.[31]
While the findings specifically mention a defendant's home or vehicle, the amendments to state code enumerated by this legislation extend to any place that a person has a legal right to be, with a few notable exceptions (such as inside a prison).
