I've learned that there's a certain degree of risk that isn't worth minimizing. It becomes prohibitive in terms of time or effort or money or even will to chase down every last specter that might go bump in the night, maybe.

Add to that the necessity for a good leader to not get caught up in every tiny detail lest they be immobilized, and you have a good picture of our Vice President's sketchy and inconsistently applied 1% doctrine. Chasing down even heinous threats that have only a minute chance of occurring doesn't sound to me like effectively safeguarding us from terrorism when there are so many credible and immediate threats to our safety; it sounds like flailing without a good plan and losing sight of the target.
