Most shooters will have some shaking. Holding your arms fully extended away from your body is not a natural position, the body must adapt and the proper muscles must be conditioned over time. A proper stance and a repeated, consistent shooting method will eliminate most of the shaking. Hold a gallon of milk with a fully extended arm and your wrist termed inward...see how long you can do it before your arm starts to shake,,,same concept, not necessarily a medical condition.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)
"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
