Amateur sleuths exposed what the intel agencies tried to hide about Wuhan lab leak story

 Newsweek;

The people responsible for uncovering this evidence are not journalists or spies or scientists. They are a group of amateur sleuths, with few resources except curiosity and a willingness to spend days combing the internet for clues. Throughout the pandemic, about two dozen or so correspondents, many anonymous, working independently from many different countries, have uncovered obscure documents, pieced together the information, and explained it all in long threads on Twitter—in a kind of open-source, collective brainstorming session that was part forensic science, part citizen journalism, and entirely new. They call themselves DRASTIC, for Decentralized Radical Autonomous Search Team Investigating COVID-19.

For a long time, DRASTIC's discoveries stayed confined to the strange world of Twitter, known only to a few nerdy followers. The sleuths ran into a fair number of dead ends, got into the occasional spat with scientists who disagreed with their interpretations, and produced a firehose of reporting. Gradually, the quality of their research and the rigor of their thinking drew a larger following, including many professional scientists and journalists.

Thanks to DRASTIC, we now know that the Wuhan Institute of Virology had an extensive collection of coronaviruses gathered over many years of foraging in the bat caves, and that many of them—including the closest known relative to the pandemic virus, SARS-CoV-2—came from a mineshaft where three men died from a suspected SARS-like disease in 2012. We know that the WIV was actively working with these viruses, using inadequate safety protocols, in ways that could have triggered the pandemic, and that the lab and Chinese authorities have gone to great lengths to conceal these activities. We know that the first cases appeared weeks before the outbreak at the Huanan wet market that was once thought to be ground zero.

None of this proves that the pandemic started in the Wuhan lab, of course: it's entirely possible that it did not. But the evidence assembled by DRASTIC amounts to what prosecutors call probable cause—a strong, evidence-based case for a full investigation. It's not clear that the best efforts of the U.S. and other nations to investigate the lab-leak hypothesis will ever turn up unequivocal evidence one way or another, at least without the full cooperation of China, which is unlikely.

There is much more including how they were able to uncover the evidence.  There are still many questions about those responsible for tweaking the virus and more importantly the cover-up which extended around the world.
