Let me see if I understand what you are saying here. You go for an ultrasound and they find a mass. The doctor states that in his OPINION it is benign but to be 100% certain they would like to do a biopsy to confirm it.
From what I can see here you are willing to bet your life on the judgment of one doctor. What if he is wrong?
Luminol reacts to 240 things one of which is blood. The same theory applies to luminol. Just because luminol reacts does not confirm that it is blood thus a 2nd test is done.
We already know Stephanoni perjured herself on the stand. Why would anyone trust what she has said?
As per the Innocence Project:
"Unvalidated or improper forensic science is a leading cause of wrongful convictions. In more than 50% of the DNA exonerations nationwide, unvalidated or improper forensic science contributed to the underlying wrongful conviction.
These problems include: forensic techniques that have not been subjected to rigorous scientific evaluation (such as hair microscopy, bite mark comparisons, firearm tool mark analysis and shoe print comparisons); testing that is improperly conducted or analysis that is not accurate (regardless of whether the forensic technique involved is validated); and forensic misconduct (such as fabricated test results and misleading testimony).
