Overseer McDonald had anticipated this, and had already ordered security to shoot any residents who tried to leave.
Vault 4 opened for the first time on August 23, 2114, and many tried to escape into the wasteland once clear of the Vault. People lived in fear of upsetting the Overseer or his security forces, and when the Overseer announced that the a scouting team was to be sent outside, volunteers thronged to sign up. The damage to the Vault was quickly repaired, and soon the security force had swelled to over 150 men. Under his rule, Vault 4 finally became politically stable, but was transformed into a police state. McDonald came through with his promise, but nothing more. In a large fight, the power structure was reversed, and the defeated leaders exiled from the Vault, dying soon after. Most residents wanted order and control, and that was that McDonald promised.
Vault 4's power structure constantly found itself changing, with no real control for any particular group, it was ony when Craig McDonald, a young man living in the Vault, rallied many factions against the most powerful faction in the Vault, that order came. The vault was to test how civilization might come from total anarchy. No resident entered the vault with a set responsibility, thus no engineers, no security, no Overseer. Vault 4 was to serve as a variation on the experiment of Vault 108, but without any controlling influence at any time.
