The Florida mother who was aquitted of murdering her 2 year old daughter Caylee? Looks like she was guilty after all.
Her defense team was able to do a forensic search of her computer and noticed that the on the day her daughter went missing, she did a Google search for the term "Fool-Proof Suffocation". Of course this information was never shared with the prosecutor, and they never found it when they looked at her computer. Her former defense attorney was very surprised that they didn't bring it up. Had the jury known this, there is no way in hell she would have been aquitted.
Sometimes the system works, and other times it doesn't.
