Johnson responds to Hillary Clinton's defensive outburst during his questioning of her yesterday.  Here's Johnson's money point:

When I questioned her about the misinformation disseminated for days by the administration, most notably by Ambassador to the U.N. Susan Rice on Sunday news programs five days after the attack, she asked, "What difference does it make?"

If you don't expeditiously debrief the people who witnessed the attack, how can you understand who initiated it, what weapons they used and who may have been involved? How do you initiate a proper response if you don't know what transpired? How do you move properly to protect other American assets and people in the region? How do you know what failures occurred, so that you can immediately correct them, if you have not debriefed the very victims of those failures? And lastly, how do you tell the truth to the American people if you don't know the facts?

Johnson's point is this: the misinformation spewed by the Administration for days after Benghazi was either rank incompetence or intentional lies told to the American public. Johnson is right; whether Americans know the truth makes a difference.
