A well regulated militia or not

One of my favorite movies is “Tombstone,” about Wyatt Earp and his brothers. In one pivotal scene, the bad guys come into town carrying their guns. Virgil Earp wants to go after them, and Wyatt is arguing with him. Virgil says, very simply, “They’re breaking the law.” When the Earps attempt to enforce the law, the result is the famous gunfight at the O.K. Corral.
