For a detective or street police, the only real satisfaction is the work itself; when a cop spends more and more time getting aggravated with the details, he's finished.

I don't consider myself to be a crusader of any sort. I was bystander to a certain number of newspaper crusades.

In the wake of Katrina, what you're witnessing and what we are very careful to depict is a form of patriotism.
