Casey Anthony is Guilty

So I know this is a little different from what I usually talk about but how exactly was she not guilty? I haven't followed the whole trial but I know enough (because anyone who actually turns on a radio or TV or reads, hmm pretty much anyone who has conscious thought knows about this trial), I know she is guilty.  I'm very ashamed at our judicial system. Not giving her the death penalty would have been fine but she should have gotten life in prison at best. I just wonder who exactly they could find her not guilty of child abuse. This is wrong.
