Metalhead is correct ... in some states. Ohio used to have the same stipulations. The "Castle Law" ended that. Now, you do not have to run,, hide, barricade, or anything else, in order to stay safe. You can shoot. Ohio also goes a bit further, defining your front porch, your car (if you are in it), even a tent (again, if you are in it) as a "Temporary domicile" and you may defend it the same as your home. Unfortunately, some states are behind the curve on this one. Now, I really AM done. Out.
