"Castle doctrine" laws are a Very Good Idea that protects citizens who defend themselves from being second-guessed by civil and criminal courts after the fact. Since a peaceful person thrown into a dangerous situation doesn't have the time and leisure to reflect on levels of risk and legal complexities that the court enjoys, it's despicable for laws to make said peaceful person risk a life-ruining felony conviction when a criminal sustains the injuries that are and should be an inherent risk of his chosen profession.
Not everybody agrees. New Jersey Democratic State Senate President Stephen M. Sweeney comments on the possibility of a castle doctrine law in the Garden State:
"All residents must be able to protect themselves in their own home when they feel their life is in imminent danger, as our laws currently do," Sweeney said in an e-mailed statement.
"However, there is a difference between legitimate self-defense and shooting someone on the way out the door with your cell phone."
"Don't you understand?! We _have_ to put innocent people at terrible legal risk for defending themselves! A thief could get _killed_!"
