..Maybe it is the economy and they think that with the attention and ratings and stuff, they can make money off of killing their kids? Who knows. Maybe the Caylee drama has stirred up some crazies to copycat it? Lord knows there are enough varied crazies out there for that to at least be considered.
Are people and parents more fucked up than they used to be? I don't think so-I just think there are more people and more info out there and it may bring out the crazy in the crazies to go ahead and act on the crazy(the attention and all).
