** Report of attempted entry attributed to OU student and OU library security guard Adam Smith (see Ch. 9 video interview - http://newsok.com/video/1634831/). Adam states that a gate security guard told him someone sprinted off after the guard tried to search the backpack he was carrying. This reportedly happened at Gate 6 - per 9 news. You can read Adam's statements from a Tulsa World article - http://www.freerepublic.com/focus/f-news/1498353/posts .
