"Son, we live in a world that has walls and those walls need to be guarded by men with guns!" Dominic shouted. "Who's gonna do it? You? You, Lieutenant Weinberg? I have a greater responsibility than you can possibly fathom! You weep for Santiago and curse Carfax; you have that luxury! You have the luxury of not knowing what I know: that Santiago's death, while tragic, probably saved lives and that my existence, while grotesque and incomprehensible to you, saves lives! You don't want the truth because deep down in places you don't talk about at parties you want me on that wall, you need me on that wall! We use words like honor, code, loyalty! At Carfax, we use then as the backbone of a life trying to defend something! You use them as a punchline! I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very freedom Carfax provides and then questions the manner in which Carfax provides it! I would rather you just said 'thank you,' and went on your way! Otherwise, I suggest that you pick up a weapon and stand a post! Either way, I don't give a damn what you think you are entitled to!" ;)
Wow. That was quite a speech. Dominic sure takes his job at Carfax seriously.
It still doesn't explain why he ordered the code red on Santiago.
