Few things I'm confused about. LP told Kathi that LA definitely told him a different story, yet on NG last night he said somethign along the lines of "we strongly believe that KC left the night of the 15th." That makes it sound like speculation/opinion. Yet if LA told him, wouldn't he say something like "we were told" rather than "we believe"? If LP is lying about LA telling him a different story, if I was Lee I would sue the crap out of LP, especially if it makes his sister look guilty and his family like a bunch of liars. I just don't see LP taking that risk and making it up completely.
Second, at first I didn't think GA lied about seeing KC and Caylee leave the 16th. He told it to the FBI at a time he seemed really concerned about Caylee and was letting out all of his daughter's dirty laundry. I really feel like he wanted to help and get to the bottom of it without purposely making up a story. However, I do feel he got the dates confused. Who honestly remembers the last thing their daughter and grandaughter were wearing over a month ago? First of all, men NEVER pay attention to that stuff. Second, I can see if he knew it was going to be the last time he'd see them in a while, but according to GA it was just another day. I really think he took what KC told police the evening of the 15th and just backed up the story, convincing himself that that's what they must have been wearing/when they left.
