The doll weighs two (2.00) pounds. It is an exhibit sold by NCSBS for $ 35.00 plus handling and shipping. It has no pretense to be biofidelic. It is used at trials to illustrate criminal shaking. The other is a CRABI, an anatomical test device (ATD) which weighs 22 pounds, approximately the 50% 1 year old male. It costs about $9,200 and comes with a thick book of specifications. It is used by biomechanics in kinetic analysis. It will be instrumented to determine forces by shaking. This preliminary experiment shows how daunting shaking becomes when weight of the putative victim resembles reality. The demonstration, with the NCSBS doll, is akin to magic, totally misleading, effective to secure convictions.
