Because LP inserted himself into this case voluntarily for the media attention and because he created many of the rumors the defense used in court, and because his ridiculous "search" efforts were about getting himself noticed, not about finding Caylee except in the sense that it would get him even more attention.
He has cost the state of Florida a ton of money with his antics which almost always required a police presence. If not for him, Casey would not have been let out on bail and there would have been no protesters....I could go on and on. When it comes to lying I think Casey and LP are having a contest, I don't know which is the better bet. LP should be sued, he shouldn't be doing the suing.
