For Carlson’s claim that the virus was engineered to be true, it’s necessary that the lab-leak theory be true. But even if that theory is being given more oxygen at the moment, it’s not the case that there’s robust new evidence in favor of the virus being engineered. To some extent, Carlson (and, apparently, Jon Stewart) are doing what the media is accused of doing, but in reverse: conflating lab-leak with the idea that the virus was engineered, hoping that the renewed speculation about the former amplifies the odds of the latter.
The lab-leak theory, while now admitted to be possible, is still extremely unlikely.
