From my non-lawyer understanding of things...

Maryland courts have ruled repeatedly that although it's a duty to retreat state common law does not require you to retreat in your own home. The right to stand your ground isn't protected by statute but [there is caselaw on the side of homeowners].

> The duty to retreat also does not apply if one is attacked in one's own home. "[A] man faced with the danger of an attack upon his dwelling need not retreat from his home to escape the danger, but instead may stand his ground and, if necessary to repel the attack, may kill the attacker." Crawford v. State, 231 Md. 354, 361, 190 A.2d 538, 541 (1963). The Court of Appeals said in Crawford, a case in which the defendant fatally shot a younger man who was attempting to break into his home to beat and rob him:

IMO that's one thing MD should clean up. I don't really think that SYG matters much but the law should explicitly protect the right to self defense in your own home. People should also have better protection from civil suits if they shoot a home invader.
