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.

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.

The first week I was in Iraq, I said, "This is what I want to do. I want to be a reporter and to tell stories of people whose stories would not be told if we don't gather them." It's part of what I think of as the one-two punch of journalism. You're trying to give voice to the voiceless, and then you're also trying to hold those in power accountable, regardless of what party they're in.

What I believe in is being transparent and truthful and always trying to get the facts right. People will make their own judgment of whether or not they want to trust you based on how transparent you are with them and the principles that you bring to the game.

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.

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.

I believe that we [Americans] are making more new enemies than we are killing terrorists at this point, and I think it's time that we stepped back from this aggressive assertion that we can just go to any country and conduct lethal operations.
