> The scientific community widely agrees that the virus was not artificially engineered. Artificially engineered isn't really the question; the questions are 'is this a lab escape?' and 'if this is a lab escape, did the virus work so well on mammals pre-experiment?'. The scientists have a massive incentive not to believe that the virus is a lab escape until the evidence is overwhelming. This is a global disaster, if…
Everyone has a massive incentive to look for actual, concrete evidence for a lab escape before they draw any such conclusions. Leaving aside the uncomfortable geopolitical angle (US policy is to respond to deliberate biowarfare with nuclear weaponry), extraordinary claims require extraordinary evidence.
The Chinese military would have to be beyond stupid to go into a bioweapons program and develop a virus that mainly only targets old people, usually doesn't cause symptoms, spreads like wildfire and is therefore a huge risk to countries with large, densely packed populations. If it was a lab escape it would probably have been just part of studying SARS-like viruses for public health reasons.
2) And there is nothing extraordinary about claiming "Standards in practice were lower than the standards on paper". That is a pretty mild claim. Lab escapes of viruses are a thing.
