After finally viewing this film tonight, I think LT did see combat and has killed before despite him saying otherwise. I think he was in black ops and his military record was classified information which prevented the FBI from seeing any of his history. LT has issues too and he's definitely into denial about his past which is one of the reasons why he never replied to those letters. I think one of the reasons why Aaron wrote him was because he felt that LT would understand the conflicts that were being fought inside of Aaron's mind. I think they edited out film footage which would've explained LT's past in more detail than what was said in the film.
