She apparently just wanted to look good. She claimed to have a masters degree and didn’t have one. Didn’t they check her credentials when they hired her? She forged the signature of coworkers and spiked negative samples with cocaine. She tested 1 out of 5 samples and called the untested samples positive. Employees told management and they ignored it. Wow.
I remember a flap in the FBI labs following 9-11, something about mishandling of evidence.
What the jury sees, the jury should severely question and challenge (naturally they are told that they cannot), but that’s the way to fight this.
They select juries based on ignorance then present “scientific” evidence, and it’s not much different from accepting the word of a shaman that the chicken guts show guilt.
I was once deselected in voir dire just because I was a scientist.
