People of various fields and professions should talk more with each other.

Respectfully, it is not junk science that locks up some innocent people but it is unscrupulous prosecutors and district attorneys that utilize the results and testimony of these so called experts to secure convictions. The burden for this falls squarely on the prosecutor and his or her willingness to put these expert witness charlatans in front of a jury when they presumably know that the science of say bite marks is unproven – but that doesn’t stop them from presenting it as iron-clad.

Add in lab error, technician error, poorly trained technicians, possible contamination of samples and false positives and you have a system that is inherently unfair to those who don’t have financial means to pay for retesting in independent labs.

This is how people of means like OJ Simpson got off. Create about doubt about the science etc etc and beyond a reasonable doubt can’t be reached by a jury.

Expert witnesses are a self-regulating and accrediting for the most part in America. Prosecutors know this but still use them because they will get the proof they need to fit their theory of the crime and putting away supposed criminals gets prosecutors and judges re-elected time and time again. If you are poor or undereducated or lacking resources – you are f*cked. All people are actually not equal in the eyes of American legal system.
