For all his flaws, and he did have flaws, Bush was an honorable guy. And he still is:
When George W. Bush heard about Fort Hood, he and Laura got in his car without any escort, apparently they did not have time to react, and drove to Fort Hood. He was stopped at the gate and the guard could not believe who he had just stopped. Bush only ask for directions to the hospital then drove on. The gate guard called that “The president is on Fort Hood and driving to the hospital.” The base went bananas looking for Obama. When they found it was Bush they immediately offered escort and Bush simply told them to let him visit the wounded and the dependents of the dead. He stayed at Fort Hood for over six hours and was finally asked to leave by a message from the White House. Obama flew in days later and held a “photo ” session in a gym and did not even go to the hospital. All this I picked up from two soldiers here who happened to be at Fort Hood when it happened.
