See at Deliberations “The Real Danger from Casey Anthony’s Trial: Scary Scientific Evidence“. Excerpt:
A cause of death that cannot be determined by the State’s medical examiner, but can be asserted on the stand by an anthropologist who has never done an autopsy. The morphing of a projected child’s photo into a picture of her skull. The description of a colorless decompositional fluid (which is typically black). Air samples that contain “the smell of death.” A phantom image of heart sticker that “disappeared” before the examiner could return to photograph it.
