That doesn't matter _if people don't trust the hospitals_. Whether or not there's a reason for it is insignificant.
> as I've not seen the alleged behaviour at all
As an aside, one anecdote doesn't mean that there's no reason to mistrust the hospital. I have elderly relatives in care homes, and I've not seen them abused. That doesn't mean there's not a problem with abuse in care homes here in the UK
While I've heard anecdotally that this happens, I find it hard to believe that this happened during the second wave when hospitals were, in general, being overrun with patients and running out of beds and oxygen cylinders. Why would you want to risk getting caught doing this when you anyway have a long queue of prospective patients waiting for a bed?
