This is legitimate reason to have a good investigation and find out the real cause of the virus. From pure technical point of view it is absolutely right.
However because of the cognitional defects of our cave man brain due to the quick social and technology progress outpaced the nature evolution process, the OP's strategy shows wisdom. Let me explain:
There are 3 cases that can present the same reason:
1.Your case which I think it's sincere request for improvement of the procedure to avoid future disaster.
2.There's a known hidden agenda based on some ideology but asking for investigation. A good example is what Dick Cheney and a group of his associates did. They had no interests to understand truth. A reason for investigation is a excuse for fool people
3.(This one is difficult to understand) There's an unintentional hidden agenda mixed with the legitimate reason that the guy who ask for truth might not be aware of hidden agenda. There are a lot of example in another community not available to English reader. The closest example is Australia Prime minister Morrison. It's very controversial and speculative. Most HNers' won't have the necessary insight to understand this example but I believe presenting a weak example is better than nothing.
With case 2 and especially 3, OP's strategy is better than yours. That's why I said OP's shows wisdom: Avoid conflicts and more loss as a whole.
Sometime a correct conclusion in the scope of leaf could be a wrong conclusion in the scope of tree. But maybe correct again in the scope of Forest. I'm not claiming my conclusion is better than yours. I might be in the "tree" level. I'm saying you are looking at a pure technical point of view. OP's thinking is bigger.
(edit) reformat and word correction
