I believe that one of the most important institutions in a democratic society is a free press.

Everywhere you go, people have recorded or captured events in real time on their mobile phones. It becomes one of the first questions you ask when you go in to investigate something.

My philosophy about journalism is simple - that we have a job to hold those in power accountable, to give voice to the voiceless, and to provide people with information that they can use to make informed decisions about what policies they want enacted in their name and what policies they don't.

If you're a human being, you'd have to be terrified. The impunity ... That these guys can sit on a TV show and just chat in a relaxed way about killing people like Julian Assange. They're joking, but at the same time, it's a vicious kind of rhetoric. The degree of enmity and the show of power and force against Assange must have terrified him. He was prepared to be paranoid when he was young - when nobody was actually after him. But this easy kind of vitriol and hatred that you now see as part of common discourse, it's become part and parcel of our everyday chatter.

For much of my life as a journalist, I've viewed myself as being embedded with civilians and with those people who live on the other side of the barrel of a gun.

I think we [Americans] are going to look back and realize that the civil liberties that we've given up in the name of security, the authority that we've given Democratic and Republican presidents, all have contributed to a fraying of the fabric of our democratic republic.

Now, here we are, and we have Obama in office, and he has drawn down forces in Iraq - which is a plan that was on Bush's desk the day that he left office. The forces in Afghanistan, he's going to draw down, too. But at the same time, Obama has also expanded a lot of the more unsavory, covert aspects of the wars, with the drone strikes and some of the night-raid missions.
