States not run by pansy DemocRATs generally don't require one to retreat.
In most states, you must retreat if you are outside of your home. There are a few states which do not require you to retreat if you are outside of your home, but they are a very small minority. None of the states require you to retreat while inside your home, provided your attacker is not legally in your home.
Laws are written in standard English. (except, maybe, in Kalifornia, Texas, AZ, etc., ) If you can read and comprehend the English language, just read your state's code on s.d., concealed weapons carry, etc.
I have to disagree. First off, the words in the statute often have meanings that are different from the usual usage. For example, Massachusetts General Law has this particular gem:
(6) A firearm identification card shall not entitle a holder thereof to possess: (i) a large capacity firearm ... or (ii) a non-large capacity firearm ...
So, if a MA FID won't let you possess a non-large capacity firearm or a large capacity firearm, what will it let you possess? It let's you possess some rifles and shotguns. How does it do that? Under most sections of MA law, rifles and shotguns are not firearms. The word "firearm" is defined in MGL Chapter 140 Section 121:
“Firearm”, a pistol, revolver or other weapon of any description, loaded or unloaded, from which a shot or bullet can be discharged and of which the length of the barrel or barrels is less than 16 inches or 18 inches in the case of a shotgun as originally manufactured; provided, however, that the term firearm shall not include any weapon that is: (i) constructed in a shape that does not resemble a handgun, short-barreled rifle or short-barreled shotgun including, but not limited to, covert weapons that resemble key-chains, pens, cigarette-lighters or cigarette-packages; or (ii) not detectable as a weapon or potential weapon by x-ray machines commonly used at airports or walk- through metal detectors.
If you don't understand that the word "firearm" effectively means "handgun" in most (but not all) MA laws, then you will come to some very grievous misunderstandings. There are plenty of other gotchas in there as well -- for example, defensive sprays are considered "ammunition" in MA law.
Also, even if you think you have a "perfect" understanding of the statute, you only understand part of the law. The courts have interpreted many of these laws, and the written opinions of the higher courts constitute precedent. Their interpretations can sometimes be described as creative and may well not be what you would expect based on reading the statute.
I'm not a lawyer. I have studied MA firearms law. I still contact the MA firearms association, the Gun Owner's Action League, and a firearms attorney from time to time. I suggest others consider doing the same, particularly when it comes to self defense. If you misunderstand the laws of self defense in your state and you act based on that misunderstanding, the consequences can be horrific.
