It recently dawned on me what should be the most obvious argument for the individual right to “keep and bear arms.”
The primary purpose of the 10 Amendments that form the Bill of Rights is to protect the natural rights of the individual from an encroaching federal government function. The only way someone would not know this is if they have not read them.
In fact, each of the Bill of Right’s 10 Amendments – there were originally 17 – states this by use of the words person, people, owner, or accused. The only two that do not expressly state the individual are the Seventh and Eighth. They do, however, use inference to make the point that both pertain to the individual.
