This is indeed a tragedy, and is incumbent on those left behind to learn from this, regardless of cause.
What is certain is this presentation of our own mortality, our abilities and responsibilities is now up front and very personal.
We cannot, and indeed should not take for granted even the slightest issue with our profession.
Who is right is never the issue; what is right will always surface.
My condolence to the Families and friends.
Yet another tragic loss.
