That no new gun laws shall be made without the express consent of the people. This meaning put to a vote by the people. Not through representatives. This includes executive actions.

Because I as a supporter for the second amendment and my natural right to defend myself from any threats to myself or those I care about, as well as yours is slowly being stripped away. And I cannot abide this type of slow tyranny.
