The transcript was certainly poor. I do not know if that is just the way it is for first draft?
However, even listening direct to the audio it is extremely difficult to fathom what the dickens Lee is talking about. He really does speak in some sort of code. Actually the impression I get is his level of english is very low. He often does not complete a thought as a coherent sentence. It is a very confused thought processes and speaking ability that cause the break down in formulating and arranging ideas. That leads to gaps which he annoyingly fills with "you know" when plainly we don't know, because he has not said. In my view he may be appearing worse than he really is because the gaps and half formulated thought are a result of excessive spin and arrangement of what he is about to say so as not to give too much away. Or put simply, he is preoccupied with making up bits of the story to suit, rather than simply telling the truth. I would guess that FBI could write a book based on a Polygraph test of Lee? All the needles would be hard over from start to finish.
