This is the curious part about criminal justice, which like jury nullification, bribery and witness intimidation, people would very much prefer to conclude as non-existent: evidence contamination and tampering, despite auditable records for chain of custody for artifacts of evidence. Consider that sometimes, lab technicians seem to fake drug test results, for whatever reason: https://www.chemistryworld.com/news/crime-lab-chemist-accuse... https://www.texastribune.org/2013/03/27/after-drug-lab-scand... https://www.nhregister.com/news/article/Chemist-at-Boston-la... It's very modern to hold up these examples of trace evidence proving incredible stories, but trace evidence exists behind the veil of highly technical instrumentation. But, as long as someone can get out in front of the scientists and the instruments, if the principle is simple to comprehend, and there exists a motive and enough power to control the outcome, it's still possible to game the system. If the samples of bodily fluids in evidence sat there since 1992, and the crime were actually committed by someone capable of framing such a crime, which was committed carefully enough to prevent effective prosecution to begin with, in order to successfully frame the patsy, they'd need to intervene and place bogus samples at both points in the evidence chain, or simply bribe all the lab technicians providing expert opinions. You might question how or why. Well, they wouldn't need to perform the chewing gum operation, until after they cemented the bogus semen in the original evidence locker. What would motivate someone to go that far? Well, pulling strings comes easy to some people, and history shows us that those people frequently aren't above murder. So framing a random semen donor comes naturally to the situation. The motive, of course, would be to protect themselves at all costs from prosecution. It's easier to buy the story that genetic evidence or other circumstantial evidence exonerates the wrongly convicted, because those that benefit are otherwise powerless. Unfortunately, given the premise of so many exonerations, it shows us that convictions can be wrong, and that cold cases should still be reviewed with serious scrutiny, especially the ones that seem like extraordinary long shots or somehow might be seeking glory. |
