Yes, the skepticism has to end somewhere. But when someone is facing years, or life, in prison, that skepticism absolutely should not end before it validates the primary evidence of guilt, and the tools used to purportedly analyze that evidence. If you can't validate the equipment used to analyze the DNA, gunshot residue, or other scientific evidence, then that evidence should not be allowed in court, because that's prima facie reasonable doubt.
