What do they mean by “registered” firearms?
The shocker for me was DC #2. What do they know?
From the article:"NFA firearms only include the categories regulated by The National Firearms Act of 1934: machine guns, short-barreled rifles, short-barreled shotguns, suppressors, destructive devices like bombs and grenades, concealable devices with the ability to discharge a shot through the energy of an explosive, and any firearm with a bore over half an inch that has not been determined to have a legitimate sporting use."
I live in one of the most 2A unfriendly states in the US and I do not own a single firearm that is required to be registered -- by the feds, the state, or local gov't. And I am a 100% law abiding citizen.
This "study" is kinda like counting the number of $250K exotic sports cars in a state and concluding how fast the average citizen of the state drives.
