  1. Fallout 3 Official Game Guide Game of the Year Edition p.88: "Officer O'Brian
    Lightly armored and keen to deliver a bit of punishment to the Vault civilians, Officer O'Brian is a vicious, unthinking man who delights in the pain of others. The confusion of the Lone Wanderer's escape makes his violent tendencies all the more easy to hide."
