I wouldn’t make that wager either… but I’ll say that I wish we were entering such an era. It would do this country some good. Happy to take further thoughts to the spinoff threads.
I think it’s overwhelmingly likely (99%) that the perpetrator is: 1) a pissed-off policyholder/family member of a policyholder, or 2) a disgruntled UHC employee. I’ll give 1% to the other possibilities floated here – gambling debt! business rival! jilted lover! – which, frankly, strike me as fantastical (and a gross violation of Occam’s razor, to boot).
And if it proves to be door #1 – pissed off policyholder – let me further hypothesize that The Propoganda of the Deed will indeed turn out to be a secondary motive. (With the primary motive, of course, being the whole pissed off/revenge thing.)
