I. April of 2012. Pilots actually sultan. Alexis Jones hardy was a freshman cadet at the United States Air Force Academy. You know he's putting his hand down my pants. And you know I kept saying no. Listen now about thirty times. She is speaking publicly tonight for the first time still angry about how she was treated not only by her alleged attacker but by the academy. Where she dropped out her life changed forever. Honestly give up on live they would times I didn't want to be alive. They don't want people to know that sexual assault as a problem at the air force academy. As a school that trains the country's future military leaders. The air force academy in Colorado Springs is supposed to be a place of strict discipline. Within under a code inscribed on the walls for all policy. We will not lies steal or cheat nor tolerate among us anyone who does. You take an honor if you promise to uphold the skaters in this country. And to be honorable but her attacker she says was a member of the air force academy's football team. While she recorded its she'd never named for alleged attack for fear he would be protected and she would be the one put on trial. I had to teammates Koehler sold ten. Colin was raped. Line in. Illicit attempt to create and solid it to them I song for the academy as a whole. Judge him. Every seeing about their personal life was put it in the fourth current. Everything anyone and they never slept too it. That was a widely held view with the air force academy according to Brandon he knows the agent with the office of special investigations the US side. Assigned to investigate sexual violence and members of the football team. Enos said the total bond did not seem to apply to many of them it is very difficult to get into that circle and they usually don't. A snitch for lack of a better word. But special agent Brandon Enos found a way to break that code of science. Within under cover cadet by the name of Eric Thomas a soccer and football team member who agreed to become a confidential informant. I think absolutely when we're talking not sexual assaults here we're talking about. Real crimes affecting real people. And having consequences that lasts a lifetime Thomas worked for almost a year as a confidential informant for eight casinos and the OS operating. The two met secretly indicted out of the way locations on the vast academy campus as Thomas who often wore a secret tape recorder. Provided detailed reports on his fellow cadets alleged criminal behavior and misconduct. I heard of a sexual assault I would report information on providing. Is what every other cadet should provide. Thomas was a gold mine of information for you knows. Leads developed by him and others resulted in what the air force called operation gridiron. Whose results were not widely publicized until the Colorado Springs gazette revealed the case late last year. Two members of the football team court martialed for sexual assault. Linebacker Jameel cooks in wide receiver Tony Kenyans both now appealing their convictions. A third star player Asher Clark was distant rolled for drug use along with fourteen other cadets many of an athlete. Expelled or forced to resign. There's actually the largest and most successful operation to ever be ran the academy without Eric would you have been able to learn that isn't. Now I can confidently say there have been no conviction. I think every product is there. Without her right. Once it became public operation gridiron put a cloud over the good name of the air force academy we haven't. Microscope over has actually we know that because we are held to a higher standard the new superintendent. Lieutenant general Michelle Johnson says she's the first to acknowledge there was a serious problem with sexual assault at the Kennedy. And she says she's made it her highest priority to fix we acknowledge it we own it. And we want to move on and we want to do better there's no denial of what happened here now. It was bad yes the air force academy says what ever happened in the past sexual violence is not and will not be tolerated. It's produced this video to help prove featuring top cadet athletes outlets such plants and close. 08 on the north side. I'll make every effort to fix an environment and even if I'm not directly part of the problem. And the academy selected for cadet athletes to reinforce the message that everyone has to stand up to sexual violence. We know we're right now that we're not that time that type person the Indian do you feel that there's a problem than it gets addressed. Yes or. Again for right now at this town media.

That I was being this moment I had my rape removed from the middle of the squadron want to miss her role Mike sets down to the elevator. And was gone from the academy. The air force has Thomas accumulated a huge number of to merits for violations. Including going off campus and attending parties. Most of which he claims we're part of his undercover assignment. I was punish. Further providing me statements without those statements. And the second.

A final decision was made by then superintendent lieutenant general Michael. If I do some rolled him from the air force academy.

Do you give Eric Thomas any credit for what he did serving as a undercover informant I don't want to talk about.
