DERRICK Z. Jackson calls for tougher gun laws (“Boston killings a game-changer?” Op-ed, Aug. 18) in the wake of the Dorchester shooting. In Massachusetts, it is already illegal to sell most replicas of a single-action 19th-century revolver. How much tougher does he want it than that?
Jackson is concerned about people who buy guns in other states with more lenient laws and bring them here. But that is already illegal.
