We are releasing this information to help people understand why we are doing what we are doing,

Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information.

The diverse threats we face are increasingly cyber-based. Much of America's most sensitive data is stored on computers. We are losing data, money, and ideas through cyber intrusions. This threatens innovation and, as citizens, we are also increasingly vulnerable to losing our personal information.

We investigate in secret so that we don't smear innocent people.

The private sector is the key player in cyber security. Private sector companies are the primary victims of cyber intrusions. And they also possess the information, the expertise, and the knowledge to address cyber intrusions and cyber crime in general.

We have built as a government something called the National Cyber Investigative Joint Task Force, NCIJTF, where 19 federal agencies sit together and divide up the work. See the threat, see the challenge, divide it up and share information.
