The only problem with the three points you list is that the first and third are contradictory. We were literally throwing away vaccines here in the United States if they could not find anyone eligible to vaccinate.
Example 1: Low-risk person forges papers to claim they're high risk or in a situation that justifies getting a vaccine Right The Fuck Now, subsequently jumping through a bunch of hoops to get a spot in a highly crowded queue.
Example 2: Person shows up at the end of the day in a vax center that is throwing away 50 doses if they can't get them in arms before people go home.
Example 1 is someone being trashy and selfish, stealing a vaccine from someone who might be able to get it today, result mostly negative. Example 2 is not stealing anything, but rather preventing a vaccine from being wasted and thus a net positive result.
Plenty of people were doing the showing up at end of day thing, it wasn't frowned on at all back in March.
And in fact holding judgement may have been the smart thing to do, given this account of the situation: https://news.ycombinator.com/item?id=27400221
Again, i don't have any more facts than before, it's still his word against the other's. But jumping on anyone's defense here is absurd unless you actually do know more (eg. You saw it unfold in the forum)
One the the people who Paul is posting these allegations about did reply here and notes that they informed the staff they qere not CA eligible, waited 4 hours, then got the shot.
It was not explicitly stated that these were shots that would have been wasted, but the 4 hour wait (if true) would seem to imply that.
To me, it implies extremely high demand - and likely the shots would not have been wasted.
I’m assuming you aren’t familiar with how these walk up sites in the Bay worked? Multiple hour long waits were common because of how high demand was in the area.
