Just jumping into the fray: at this point, the only thing out in the public domain is DISCOVERY material which will be well fought over in court to be entered in as scientific evidence. I'm going with the hope, belief and fingers crossed (very very technical procedure!) that the "sniffer" results WILL be accepted since 1. the basic scientific principle is provable,2. the results achieved are replicated by others, 3. the test results were performed with standards and controls. Then we have testimony of LE individuals with experience in the field of homicide and body retrieval, we have a small detail called adipocere present in the "cover-up" trash bag, testimony of a family member who also has had past life experiences in LE and the coup de grace, the spontaneous utterance of the Grandmother of the YEAR! As in every case, the State presents its courtroom story grain by grain of sand until a dune is formed that smothers the defendant in reality.
And.....that pesky "death banded hair sample" that is similiar to that of Caylee's hair: remember, NOT chemically treated, mtDNA of the Anthony ladies who DO have chemically treated hair and, as Casey so aptly mentioned....giggles.... are alive!
