Those who believe circumstantial evidence is meaningless would agree with you.
I don’t think circumstanial evidence is meaningless. But from the evidence I heard, I can’t say for sure Casey caused Caylee’s death. I can’t say it wasn’t an accident or that another person caused Caylee’s death. From pictures of Casey with Caylee, she seemed to love her daughter. There were no reports of abuse. I think Casey has serious mental problems, one being a pathological liar. But I just didn’t see enough evidence that she murdered her child.
