Just read an exchange on scent packets as possible evidence on hatfield.There are at least 2 cases led by scientific experts that led to wrong guilty verdicts in au. 1 was a case where flakes of paint obtained at a suspects house led to his conviction for murder.It was suggested at the trial a high force hurricane would be required to move the flakes into the suspects house.Turned out all the houses in the district had the same air borne flakes.Convicted killer was released. The other case was Azaria Chamberlin's.Scientific evidence was later found to be mistaken and she was released.These are just 2 cases that I know of offhand in au. http://cryptome.org/hatfill-scent.htm The care and handling of scientific evidence is another contentious subject,it has also led to possible wrong verdicts,such as OJ's.To be on the safe side though, it may be wise to scrub up well,use 2 sets of gloves with lots of cayenne pepper and take lots of showers when sending anthrax letters.Also don't provide so much fucking text you drongo.
