As a communication medium, social media is a critical tool for terror groups to exploit.

Unfortunately, changing forms of Internet communication are quickly outpacing laws and technology designed to allow for the lawful intercept of communication content.

Technology has forever changed the world we live in. We're online, in one way or another, all day long. Our phones and computers have become reflections of our personalities, our interests, and our identities. They hold much that is important to us.

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.

Only a crazy person wouldn't fear approaching a car with tinted windows during a late-night car stop, or pounding up a flight of stairs to execute a search warrant, or fast-roping from a helicopter down into hostile fire. Real agents, like real people, feel that fear in the pit of their stomachs.

Law enforcement's biased view of the Irish lives on in the nickname we still use for the vehicles we use to transport groups of prisoners. It is, after all, the 'paddy wagon.' The Irish had tough times, but little compares to the experience on our soil of black Americans.

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.

Public corruption is the FBI's top criminal priority. The threat - which involves the corruption of local, state, and federally elected, appointed, or contracted officials - strikes at the heart of government, eroding public confidence and undermining the strength of our democracy.

Prosecutors necessarily weigh a number of factors before bringing charges. There are obvious considerations, like the strength of the evidence, especially regarding intent. Responsible decisions also consider the context of a person's actions and how similar situations have been handled in the past.

We face cyber threats from state-sponsored hackers, hackers for hire, global cyber syndicates, and terrorists. They seek our state secrets, our trade secrets, our technology, and our ideas - things of incredible value to all of us. They seek to strike our critical infrastructure and to harm our economy.

The FBI has built up substantial expertise to address cyber threats, both in the homeland and overseas. Here at home, the FBI serves as the executive agent for the National Cyber Investigative Joint Task Force (NCIJTF), which joins together 19 intelligence, law enforcement, and military agencies to coordinate cyber threat investigations.

To accomplish its mission, the FBI relies heavily upon its law enforcement and intelligence partners around the nation and around the globe. By combining our resources and our collective expertise, we are able to investigate national security threats that cross both geographical and jurisdictional boundaries.

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.

Social media has allowed groups, such as ISIL, to use the Internet to spot and assess potential recruits. With the widespread horizontal distribution of social media, terrorists can identify vulnerable individuals of all ages in the United States - spot, assess, recruit, and radicalize - either to travel or to conduct a homeland attack.

Hate crimes are different from other crimes. They strike at the heart of one's identity - they strike at our sense of self, our sense of belonging. The end result is loss - loss of trust, loss of dignity, and in the worst case, loss of life.

I believe that Americans should be deeply skeptical of government power. You cannot trust people in power. The founders knew that. That's why they divided power among three branches, to set interest against interest.

What makes the bravery of the men and women of the FBI so special is that they know exactly what they're in for. They spend weeks and weeks in an academy learning just how hard and dangerous this work is. Then they raise their right hands and take an oath and do that work anyway.

For me, law school was a time of joy and hope. Joy in learning my way around the law - learning how to orbit a problem and to ask myself hard questions and to be asked hard questions. Hope that I could be of some use, to be part of the greater good - to make the world a little bit better.

Stuff doesn't matter - boats, cars, fancy things don't matter. What matters, what will matter to me, is the love of the people around me, and did I take a chance? Did I seize an opportunity to do something for people with the talents that I was lucky enough to be given? Did I make a difference in the lives of people who needed me?

The promise I've tried to honor my entire career, that the rule of law and the design of the founders, right, the oversight of courts and the oversight of Congress will be at the heart of what the FBI does.
