In Ohio, not only are you not allowed to use deadly force to defend property, but you also have the duty to retreat. This means that in a situation where you feel you are going to be harmed, you have to make every possible effort to escape the situation. Deadly force can only be used when it is not possible to retreat, say if you are in your bedroom and a bad guy breaks in and is blocking the doorway. In this scenario, you are welcome to pull a gun and blow the fucker away. The only time to pull a gun is when you are in immediate danger with no other alternative, and you must be ready to use deadly force. If you pull the trigger, the person on the receiving end had better be going down, or you will get fucked in the ass by the legal system (not saying you won't anyway). Remember, guilty until proven innocent, and dead men tell no tales.
