Jack Bauer on Day 1

This is a description of Jack Bauer's actions on Day 1.

Day 1
Shortly after midnight, Kim snuck out of the house. Immediately afterwards, Nina Myers called Jack into an urgent meeting with Richard Walsh at CTU where they learned of a planned assassination attempt on the life of Senator David Palmer. Walsh pulled Jack aside and informed him of a possible conspiracy within CTU to kill Palmer and to trust no one else. George Mason arrived and provided Jack with secured access to nationwide data, but wouldn't reveal the source of their information. Jack shot Mason with a tranquilizor, then gathered information with which to blackmail him. After waking him up, Jack threatened to send Chappelle incriminating evidence if he didn't reveal the source of the information on the shooter. Having no choice, Mason did so, then left CTU with threatening words.

At around 1:00am, word came in about a 747 exploding over the Mojave Desert. Jack immediately set his team on the task of finding a connection to the Palmer assassination plot. Teri called to tell him that she and a man named Alan York had tracked Kim to a furniture store in Van Nuys, however the girls had already left.

Jack got a phone call from Walsh, who was under attack at 2350 Dunlop Plaza. Trusting no one else, Walsh requested his back-up. Jack arrived a short while later and found Walsh shot in the arm. The two soon came upon the shooters and Jack managed to kill them both. He cut one of the men's thumbs off to later use as identification. Exiting the building, Walsh was shot again by a sniper. Lying close to death, Walsh gave Jack a keycard and told him to have Jamey Farrell determine who it belongs to, as the owner is the dirty agent, before he was shot one final time and killed. Jack narrowly escaped and drove towards CTU. On the way, he sent Jamey the information from the keycard and she quickly determined that it belonged to Nina Myers.
