On this post? lol Laws are not made in less than 10,000 words increments.
I'm not laughing. Please share with us how you are going to write a law that automatically determines innocence or guilt, but doesn't allow the guilty to walk (without a trial).
And criminal laws are rarely long. Shorter and clearer is best, with juries deciding the issue of applicability. Only regulatory laws run more than a few paragraphs.
The 10 Commandments and the Bill of Rights are both prime examples of concise brevity.
Here is the Pennsylvania self-defense law in its entirety. It is accompanied by background statements and a list of definitions, but here is the law:
The General Assembly finds 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.
Short and sweet, but a DA and possibly then a jury must still decide whether a homicide was self-defense. It is impossible to write laws that do not require human judgment to enforce.
