Would you care to elaborate on that statement?
I have ZERO medical training (and I didn't stay at a Holiday Inn Express last nite either,) but it seems to me that if a forensic pathologist says 4 cases received a lethal amount of morphine and they ended up DEAD, O.D.'d, it would appear that someone snuffed them, not knocked them out, so they would peacefully sleep through the emergency. AND none of the four were previously receiving morphine or midazolam doses in ANY amount prior for treatment, as the medical records of the patients show, the lethal dose would appear to have been given for one purpose - to kill them, rather than for treatment.
Assuming that the forensic pathologist knows his business, this would appear to be evidence of what the medical personnel who signed affidavits and brought the case before the grand jury were stating.
As for the MD who split after learning that they planned to kill the patients, but before the patients were administered the fatal doses, and reported it to the authorities, if I thought I could not stop the action they were about to take, I would have done just what he/she did. I would not stick around to find out if they planned to do me too, to keep me from talking.
