"Instead, the Maryland Supreme Court reached out to crush the Right to Keep and Bear Arms.
The Court pointed out that Heller and McDonald had both involved possession of handguns in the home. Therefore, according to the Maryland court, nothing that the Supreme Court said about carrying was legally binding. It was a mere "dicta." Dicta is a non-binding expression of legal opinion that is not part of a court's rationale for deciding a case. So the Maryland court concluded: "If the Supreme Court, in this dicta, meant its holding to extend beyond home possession, it will need to say so more plainly."
This is very poor reasoning. First of all, Supreme Court justices are not seventh-grade students who are trying to pad their decisions with enough words to make the paper long enough to satisfy a teacher. Everything the Supreme Court writes in an opinion is meant to instruct lower courts - especially when the Court is writing a major opinion about a subject (such as the Second Amendment) on which the Court had previously written little."
