COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]
I'm not sure how it would have benefitted the public for the government to say it escaped from a lab (even if that was the truth) at the beginning of the pandemic. It would not have changed anything that we needed to do at the time, it would have just caused us to focus on punishing China instead of doing what we needed to do to get through the pandemic.
Now that it's almost over, i can see the government slow rolling out the info that it did indeed leak from the lab (if that is what happened), especially since we are at a place where public animosity towards China might serve the interests of the government.
I am not one of those people who thinks that the government must always tell the public the whole truth. The public isn't mature enough for that sort of policy to work.
