Though no clinical studies have been conducted to determine either the validity of the assertion or the mental faculty of those making it, some members of Congress and some state Legislators believe a pistol grip on a rifle to be an actual cause of criminal inclination in humans. No mechanism has been identified, or suggested, by which such causality would manifest itself. More curious is the apparent belief among said Legislators that; A) any moderately developed Homo Sapiens would entertain such assertions and that; B) one might find articles within the U.S. Constitution which specifically grant them authority to make laws based upon said assertions.
