In Ohio you can.
Over the objections of law enforcement groups, Gov. Ted Strickland today signed into law a bill that relaxes certain gun restrictions and establishes a new “castle doctrine†for shooting an intruder in self-defense.
The legislation, Senate Bill 184, takes effect in 90 days.
It was backed by the National Rifle Association to establish a presumption that a person acted in self-defense when shooting someone who unlawfully enters his or her home or occupied vehicle. Supporters say it will protect the innocent from facing charges.
Right so you can't just shoot someone for trying to steal your bike! UNLESS you warm it up and by the time the cops get there you can say the guy tried to take it with you on it. If you did kill the thief who's going to argue the fact!
