If I've ever read this before (RE: threat of sanctions), I've sure forgotten it. Could you please provide a reference/link?
What is NDIS?
Nobody is "threatened" by the DNA in CODIS. That is a logical fallacy.
The "side" we are on, BTW, is solving this case.
Thinking that "DNA is the key to solving this crime" is a path that leads nowhere. It's a dead end.
The term "putative perpetrator" was probably nothing more than professional terminology; usual and customary when submitting such a sample. I don't see any reason to read anything into it.
The "rift" between the BPD and the DA was much more than "a failure in leadership", imo. The DA's office was a roadblock in BPD's investigation from day one, protecting insulating the wealthy R family. Had they been anything but wealthy people, things would have been much, much different.
What Hunter did was to stall at every turn and then deceive the public. What Lacy did was to become an R apologist and defender. She should have been disbarred and prosecuted for misconduct.
