Respectfully. The SEMI-AUTOMATIC AR-15 ASSAULT RIFLE was first built in 1959 (168 years after the 2nd amendment was ratified) as a small arms rifle for the United States armed forces, NOT available to the public. This model has now been the weapon of choice for the massacres in Orlando, San Bernardino, Aurora and Sandy Hook. I ask this...is it possible that just one death could have been prevented if this exact weapon were never allowed in civilian hands? True indeed a determined killer will always find a way but tell that to a mother of a child senselessly murdered by an AR-15, and I repeat, a SEMI-AUTOMATIC AR-15 ASSAULT RIFLE originally intended for the United States armed forces...ONLY!
