Other states followed Florida's lead with laws specifically affirming the right of their residents to defend themselves, even outside of their homes and with deadly force if necessary. Although some states may use a blend of self-defense doctrines, their laws generally fall into the following three categories: Stand Your Ground: No duty to retreat from the situation before resorting to deadly force; not limited to your property (home, office, etc.). Castle Doctrine: No duty to retreat before using deadly force (use of deadly force against intruders is legal in most situations); limited to real property, such as your home, yard, or private office; some states, like Missouri and Ohio, even include personal vehicles. Duty to Retreat: Duty to retreat from the situation if you feel threatened (use of deadly force is considered a last resort); may not use deadly force if you are safely inside your home.
