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

Significant officials at publicly traded companies are casually and cavalierly engaged in insider trading. Because insider trading has as one of its elements communication, it doesn't take rocket science to realize it's nice to have the communication on tape.

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.

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.

Businesses should be assured that law enforcement will operate with the utmost sensitivity toward victims of cyber attacks.

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.

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.
