It's now about 1730 and we're finishing up the day here at an observation post and right now

for about the last 10 to 15 minutes you can hear in the background the evening singing

from the minarets.

Believe it or not, sooner or later, we will kill some of these folks who need to be killed.

That's the beautiful thing about this world, is that there's always someone who needs to be killed and we're the folks to do it.

I've spent the past four years investigating a crime.

A crime that most people have long forgotten.

He heard the sound of really strong bombing.

I heard M16. A crime that for almost 20 years has gone unpunished. They went into the room and they were just taking shots.

I was just taking shots.

Me Anur, we were under the bed.

He got his rifle and started shooting at us.

How did they not perceive the theories were children?

I remember I opened a Humvee and I just see bodies stacked up.

I opened another one the same thing.

I'm like, shit.

A four-year investigation, hundreds of interviews, thousands of documents, all in an effort to see what the U.S. military has kept from the public for years.

You know, I don't know what's to be gained by this investigative journalism.

I'm not interested in talking about that.

That was a long time ago and I tried to move past all that so no thank you all that.

I'm saying it was so traumatic you couldn't talk about it.

You and you and you and you.
