This battle for 'common-sense' gun control laws pits emotion and passion against logic and reason. All too often in such a contest, logic loses. So, expect more meaningless, if not harmful, 'gun control' legislation. Good news - if you're a crook.
When you are in any contest, you should work as if there were - to the very last minute - a chance to lose it. This is battle, this is politics, this is anything.
A battle lost or won is easily described, understood, and appreciated, but the moral growth of a great nation requires reflection, as well as observation, to appreciate it.
