“Forensics labs, the study says, are funded, in part, per conviction...”
I worked for many years as a forensic chemist....and that’s nuts!! In fact, the lab where I worked would have considered that arangement to be unethical. I know because I once accepted a job along similar lines and the staff had a debate about it. I was instructed in no uncertain terms that payment must never depend on results.
Perhaps its not everyplace but its certainly more then just this one case.
