The TV show "COPS" has a MSP officer telling the subject that possession of hollow point or black talon ammo (not sure if it was black talon or HP in general) was illegal, but I don't go around telling people in my classes that such ammo is "illegal to possess in MA".
I suggest you learn to verify sources before stating something as fact. There is a big difference between "so and so stated XYZ" and "XYZ is true". When you relay it as fact, rather than someone's opinion, you are placing your credibility for accurate information on the line...
