This is an issue I make on almost every Aggravated Assault or Manslaughter case when a person's eating/drinking information is unknown. Retrograde is not a widely accepted science and there are many assumptions that must be made. I have not yet made the argument under Daubert because it is so new in Arizona. However, I have made the motions under the Rules of Evidence.
