No, widespread cases alone won't give the public grounds to support a lockdown. It depends on hospital strain, and probably (looks like) to a lesser extent, deaths.
Somewhere between "So what if we all get a cold", and "Ohmigawd, we're all gonna die".
The scope of unknowns is still pretty wide.
Take a lot of precautions, but after that - what?
There may be a point where the spectre of hospitals being overwhelmed provokes thoughts of another lockdown, but it isn't with us yet.
From where we are it's hard to tell whether it ever will, or we'll be overwhelmed in so short a period that we won't have time to affect it.
Meanwhile, relaying any figures, observations and discoveries to this forum is very acceptable I'd have thought.
Individual doctors' opinions are all very well, but they're all over the shop, varying in their degree of super-cautiousness like previous waves.
Just because they're doctors doesn't means they have common sense.
I suspect we're all getting tired of some of the silly words people are using, though.
