Is it just me or does it almost seem as though LA is very happily repeating all the lies Casey told without any problem. I watched again and while he does lie it seems like he's covering his own a$$ by saying he believes everything she says while simultaineously throwing her under the bus by providing all kinds of yummy information such as KC deleting files, the family never hearing the name ZFG before and all the other ridicuolous info KC has given them. He is actually volunteering things. The A's sure do like to talk.
In a roundabout way he looks stupid for believing KC's lies, but he's playing on both sides of the fence. By saying he believes her, he covers himself but is free to repeat all the lies and crazy stories KC has told which in turn is great for the prosecution.
I can see now why the A's really don't want to do this.
