Actually she had tried to commit suicide a few years earlier and had a known mental health issues. And I've spoken to an Indian nurse colleague who seemed to understand the gravity of the perceived shame and reasoning behind it.
I don't know about how her cultural background would have caused her to react, so I've no reason to doubt your colleague's explanation, in that case.
The story seemed to change and different details later emerged. If we go down the not-100%-trusting-the-authorities line, we have no way of knowing whether the correct information did later come to light or if there could have been later reactive excuses concocted/evidence 'discovered' to provide backup for the official line - in this or any case.
When whistle-blowers or the families of people who die in unusual or potentially suspicious circumstances suddenly shut up or retract their earlier protestations, does this mean that they know that they've been rumbled for their 'lies', may be very ashamed at having genuinely believed what they now are convinced was not true (e.g. JS's nephew), and don't bother pursuing their grievance; or might they have been given clear 'warnings' as to what will happen if they don't keep their silence? We've no way of knowing for sure one way or the other.
Or, as some people believe, the whistle-blowers might have been 'shills' to the conspiracy, deliberately put there to leak the info and then discredit it. e.g.:
- "The Royals have some bizarre and very concerning beliefs and behaviours."
- "The Royals are alleged to have been complicit in some horrendous crimes."
- "The Royals are actually, literally cold-blooded reptiles who only shapeshift to disguise themselves in a plausible human form."
Most people would give credence to number 1 and many wouldn't instantly discount number 2 as totally impossible. Once they hear number 3, you have instantly lost any credibility that you otherwise could have had, meaning that they then assume numbers 1 & 2 must also be completely invented fantasies, because YOU were the one who introduced them.
