Gov. signs bill allowing homeowners to legally kill intruders

MADISON, Wis. (AP) - Gov. Scott Walker has signed a bill that allows homeowners to legally kill intruders.

The bill, nicknamed the "Castle Doctrine," creates a presumption of legal immunity for someone who kills or injures a person breaking into his or her home, vehicle or workplace. The measure requires a judge to presume that the use of deadly force was necessary.

The immunity presumption would not apply to a shooter who attacked someone he or she should have known was a public safety officer.

The Republican-controlled Legislature passed the bill early last month. Walker signed it into law Wednesday afternoon.
