Immigration lawyer Sung-Ho Hwang stayed busy at his New Haven law practice last week, after prosecutors dismissed misdemeanor charges against him.

The charges stemmed from a communications breakdown between Hwang and police at a midnight showing of the latest Batman movie, “The Dark Knight Rises.” The conversation in the New Haven movie theater was complicated by the fact that Hwang had a pistol tucked in the waist of his pants, even though he had a permit to carry the weapon.
