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.

Unfortunately, from what I can see from my vantage point as the U.S. Attorney here, illegal insider trading is rampant and may even be on the rise.

Insider trading tells everybody at precisely the wrong time that everything is rigged, and only people who have a billion dollars and have access to and are best friends with people who are on boards of directors of major companies - they're the only ones who can make a true buck.

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.

I wanted to be a prosecutor - a criminal lawyer - because there's nowhere where the stakes are higher, where you can wake up every day and believe in what you're doing.

As the United States attorney in Manhattan, I have come to worry about few things as much as the gathering cyber threat.

From coast to coast, the FBI and Securities and Exchange Commission have ensnared people not only at hedge funds, but at technology and pharmaceutical companies, consulting and law firms, government agencies, and even a major stock exchange.
