even george graph and jonathan haul allowed us to shoot footage. a few months after michael gill was released on parole. >> coming up, our producer follows a trail of blood that leads to one of the most shocking scenes ever shown on lockup. >> we got a cut up here. >>> when our crews are filming inside high security prisons they know that violence can erupt at any moment. while they are prepared for it, when it happens it can still be shocking. >> during our extended stay shoot inside indiana state prison we walked into one of the bloodiest encounters in lockup history. >> we were filming in one of the housing units and we heard a call come over the radio instantly all staff members started running. we picked up our gear and ran with them. >> what is it? >> a fight. >> there was just a chaotic scene. by the time we got there they were already pulling people out coming back from chow. and they were trying to find a victim of what we thought at the time was a fight. >> i don't know who it involved. >> i don't know. no. i told these guys to hold up. >

graph. it's been at least a decade since we had broken through the 50%. it happened under george w. bush.ooks like it was pretty much after 9/11. and then it went way down and went up after the election of barack obama. and up and down and now down again. kirsten, what's it going to take to put us in the right direction according to americans' minds? >> i think part of it is obviously if the economy turns around and people feel more confidence. that helps. but it doesn't change the fact that people fundamentally don't trust a lot of the major institutions in this country. in this poll, the only one they seem to trust completely is the military. other than that, you see a lot of distrust, whether it's church leaders, political parties, whether it's wall street. i think the only way that that's going to change is if the people who run these institutions change their behavior. >> speaking of confidence in political parties, i want to show this last poll because it was very enlightening. confidence in the federal government, democrats say quite a bit of confidence. 25%. republicans, only 9%.
