Completely disagree.
If this were, say, an air disaster - the whole lot would be under the microscope, from the pilots who were flying to the guy who refuelled it to the folks who last did maintenance work.
Its not necessarily the intelligence or the integrity of any scientist that is in question, while that'll always be a subject that rears its head, its really whether the scientific opinion presented contained representative input and review of suitably qualified and experienced people across the board.
Robust review being absolutely critical. An echo chamber serves no-one.
We already know there was a serious neglect in onboarding of lessons from Asia in previous airborne viruses, we already know there was a dithering from SAGE early on and only when the horse bolted did they start to shut the door with regards social distancing (remember Cheltenham anyone?).
