I have come to really love the sound of nervous laughter.

We have witnessed the most educated, successful, and monied professionals in the country put their companies - not to mention their own liberty - at risk by engaging in flagrant and foolhardy illegal conduct.

History has shown that one cannot legislate a culture of integrity. And yet, one of the paramount responsibilities and challenges of corporate leadership is to ensure such a culture.

I spoke bluntly about what I had seen in a little over a year as United States Attorney for the Southern District of New York. To the apparent surprise of many in the room, I observed publicly that insider trading appeared to be rampant.

That's an incredibly serious thing if people think that the president of the United States can tell heads of law enforcement agencies, based on his own whim or his own personal preferences or friendships, that they should or should not pursue particular criminal cases against individuals. That's not how America works.

The alarm bells sound regularly: cybergeddon; the next Pearl Harbor; one of the greatest existential threats facing the United States. With increasing frequency, these are the grave terms officials invoke about the menace of cybercrime - and they're not understating the threat.

I would like to think that the level of aggressiveness in law enforcement will remain the same, when you're talking about things like keeping the markets fair and government honest. I don't foresee any departure from that, unless I'm missing something big.
