As I've seen over and over again during my career, the best way to deter individual conduct is the threat of going to jail. That's what truly changes behavior. That's what changes the calculus as employees and executives decide whether to participate in an illegal scheme.

At the risk of sounding really corny now, I'm a career prosecutor. I've been doing this for a very long time. And I believe in holding people responsible when they violate the law. But our sole responsibility is to seek justice. And sometimes that means a very lengthy sentence for people who are dangerous and from which society must be protected.

There is one system of justice, demanding that all be held accountable when laws are broken.

My responsibility is to ensure that the position of the Department of Justice is not only legally defensible, but is informed by our best view of what the law is after consideration of all the facts.
