Duty to Retreat States

On the other end of the legal spectrum, some states have laws imposing a duty to retreat. A duty to retreat generally means that you can't resort to deadly force in self-defense if you can safely avoid the risk of harm or death (by running away, for example). If that is not an option, say if you were cornered or pinned down and facing serious harm or death, then you would be authorized to use deadly force in self defense. The following states impose some form of duty to retreat before using deadly self defense:

Arkansas Connecticut Delaware Hawaii Iowa Maine Maryland Massachusetts Missouri Minnesota Nebraska New Jersey New York North Dakota Rhode Island Wisconsin Wyoming
