The mother of Pat Tillman is speaking out about her son’s death in her first television interview, to be broadcast this Sunday on 60 Minutes.

The Tillman family has spent years trying to get at the facts of what happened and who was responsible for the cover-up. Even today, they are not convinced it was as innocent an accident as the military claims.

“When I heard it was a friendly fire, I felt terrible for these soldiers,” Mary Tillman stated. “I still do to a degree, but I don’t think it was the horrible accident that they like to play this out. I think there was huge negligence involved here.”

“This isn’t about us,” Mary Tillman told CBS. “This is about what they’ve done to the public. This was a public deception.”
