Areas of disagreement about the knife. DNA-advocates allege it was cleaned with bleach, but DNA-critics have documented that bleach destroys DNA. It seems to be agreed that bleach also destroys blood. Therefore, if bleach were used it would have to react with blood much more slowly than with DNA.
One DNA-advocate claims that there was no noise in the data. Another DNA-advocate may believe that the signal-to-noise ratios in this case are sufficient. The DNA-critics respond by noting that spectroscopy generally has finite S/N ratios, meaning that the noise is not zero. The S/N ratios of the fluorescence peaks are tabulated along the x-axis in Figure 1 of the petition. They can also be read by referring to the y-axis. The amount of noise can be estimated by looking at the squiggly stuff between each peak in Figure 1. It would be helpful to learn what criterion for peak rejection was typically employed in Dr. Stefanoni’s lab.
