Original sentence: There is some difference of opinion as to how revolutionary the events of 1688-89 actually were, some commentators argue that the right to bear arms originated in 1689 when the traditional duty to arms evolved into the right to arms, and other commentators make the point that the provisions of the Bill of Rights did not represent new laws, but rather stated existing rights.This seems to have concerned some Americans more than it has the English  and over time parliaments have continued to refine the definition of "as allowed by law" by passing law over classes of weapons (such as knives, swords, hand guns and rifles)
