I realize the insanity of trusting Wikipedia for any kind of exhaustive legal analysis. But they’ve got a great list, and the list (for the most part) links to the relevant statutes. If I was really going to be serious about this I’d take the time to look up state murder law for all 50 states on Westlaw and verify that the states listed have some version of a justifiable homicide excuse for people in their own homes. But for now, Wikipedia will have to do.
Here is the updated list of the states which have adopted some form of Castle Doctrine law, as of June 21 2008.
Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Washington, West Virginia, Wyoming
Check the Wikipedia page for updates and for the distinction between “no duty to retreat” states vs. “no duty to retreat in your own home.” There is obviously a difference.
And just for giggles, here’s a link to a castle doctrine map from the NRA. There is no date attached to this map so I have no idea how current it is- for example, they’ve got Ohio but they’re missing Utah and Hawaii so it’s not immediately clear when the NRA map was created or what it represents.
Remember, I’m not a lawyer, and this is not legal advice- if you’re wondering whether you can shoot a home intruder in your state, this represents what I think is a pretty good guess, but you certainly shouldn’t bet your life on it.
