Casey Anthony innocent?

Now that I have your attention. For those who are believing that Caylee drowned. The fact has been proven that Casey was out partying after that baby "went missing". So even if it was an accidental drowning, is this the way a loving mother acts? Where was the grief???? No one will probably ever know the truth about what happened. The innocent one in this case is now dead and gone and so undeserving of her little life being taken from her.
