[edit] Day 5

As Jack Bauer interrogated President Charles Logan on his involvement in the day's events, holding a gun to his head, Logan attempted to plead with Bauer by saying that he would go down in history with Booth and Lee Harvey Oswald while Logan would be written as a hero alongside Kennedy and Lincoln. Bauer was unable to shoot Logan.
