We in the gun community are fond of saying that the Second Amendment guarantees Americans the means to overturn a tyrannical government.  The words of the Founding Fathers prove they intended an armed citizenry serve as a check on government power.  Gun owners have tended, however, to avoid discussing the question that must inevitably follow.  What oppressions by the state make an armed uprising morally right?  I asked several writers to address this question, and most instinctively shied away.  It's not an easy or comfortable topic.  Clayton Cramer, however, is not one to let a tough topic dissuade him, as readers of [i]SHOTGUN NEWS[/i] columns know well.  What follows may provoke you or disturb you, but these are words that needed to be written and need to be read.
