Both U.S. political parties are now open to the idea that Covid may have come from a lab in China.A new House committee investigating the origins of Covid opened its first public hearing yesterday with plenty of political theater. Republicans accused Dr. Anthony Fauci of covering up the virus’s origins, and Democrats criticized those claims as biased and unsubstantiated. But lawmakers displayed bipartisan agreement on one point: The virus really may have come from a laboratory in China.“Whether it was a lab leak or infection through animals, I think we’ve got to pursue both of those paths if we are ever to get the truth,” Representative Kweisi Mfume, Democrat of Maryland, said.Such agreement might have been surprising not long ago. From the start of the pandemic, the idea of a lab leak was fraught. Some scientists treated it as an outright conspiracy theory. Many Democratic politicians, journalists and others instead embraced the explanation that the virus jumped from animals to humans.Now, the F.B.I. and the Energy Department, which employ leading U.S. scientists, say a lab is the likely origin. But they remain uncertain, and four other U.S. intelligence agencies say, with low confidence, that it more likely originated in animals.Today’s newsletter will explain the debate over the theory and why it matters.What’s the lab leak theory?There are actually multiple lab leak theories.The most plausible is that the virus accidentally leaked from a lab in Wuhan, China, where scientists may have been studying it, and possibly engineered it, for research and medical purposes.That theory differs from the claim that lab scientists created Covid as a bioweapon or that China intentionally leaked the virus. Neither experts nor U.S. officials take that assertion seriously. “It is an important distinction,” said my colleague Sheryl Gay Stolberg, who covers health policy.What is the case for each explanation?The natural origin theory: Animal-to-human transmission is the predominant origin of viral diseases, including other coronaviruses and bird flus. Many of the first confirmed Covid cases were linked to an animal market in Wuhan, and live mammals there are known to spread viruses.The lab leak theory: Wuhan is home to an advanced virus-research lab and the Chinese C.D.C. — ties that lend credence to the idea of a lab leak, much as the animal market’s presence does for the natural origin theory. Chinese officials’ apparent destruction of evidence adds to the suspicions of a lab leak. Biological labs around the world also have a history of accidental leaks.Even many officials and others who lean toward one of the two theories remain uncertain. U.S. officials are divided and acknowledge they are working with imperfect information, largely because China has not allowed an independent investigation within its borders.Why does this debate matter?For many, determining the cause of a pandemic that has killed nearly seven million people worldwide, including 1.1 million in the U.S., is important regardless of broader implications. Basically, the truth matters for its own sake.The Wuhan Institute of Virology.Hector Retamal/Agence France-Presse — Getty ImagesLearning the origins of Covid could help save lives, too. If the virus came from an animal, then studying and tracking the spread of viruses in nature could be crucial to preventing the next pandemic. If it originated in a lab, then improving the security and safety of virology labs might be more important.And if both theories seem plausible, that is a case for doing more to prevent animal-to-human transmission and future lab leaks. “Some scientists argue there’s more to be done on both fronts,” said my colleague Benjamin Mueller, who covers health and science.Why the lab leak skepticism?Some scientists who initially dismissed the lab leak based their views on earlier, incomplete evidence. At first, experts embraced the animal market explanation because some of the first confirmed cases, from December 2019, were linked to the market. But researchers later discovered that the virus may have been spreading weeks earlier, and it is not clear that those cases were linked to the market.Typical human bias probably played a role in the skepticism, too. “Scientists are human, and science has become a vested-interest industry,” Tim Trevan, founder of the safety consulting company Chrome Biorisk Management, wrote in The Wall Street Journal.Early in the pandemic, the lab leak theory became politicized when Donald Trump and his allies began promoting it. Many experts took sides, as did much of the public. Some may have also feared that blaming scientists for Covid could have vilified their industry and hurt the funding they rely on. The dynamic is a reminder that experts are also susceptible to biases and self-interest like the rest of us.Will we ever know the origin?Probably not. Pinning down the origin of a virus is inherently difficult. China has made the task harder, blocking outside investigations and refusing to share data on the virus’s spread.But the investigations, including the House’s, have already spurred discussion and debate about better tracking of animal viruses and improving lab security. Those steps could help save lives even if we never know what really caused the Covid pandemic.For more: “Assigning blame is not going to bring back seven million people” The hearing showed the difficulty of uncovering conclusive evidence about Covid’s origin.THE LATEST NEWSPoliticsMitch McConnell, the Senate minority leader, was hospitalized after tripping at a Washington hotel.“I hate him passionately”: Tucker Carlson’s texts show contempt for Trump.

Memphis’s Scorpion is the latest special police unit to come under scrutiny.The Memphis police officers charged in the death of Tyre Nichols were part of an elite unit known as Scorpion that was set up to crack down on high-crime neighborhoods. The officers’ actions as they stopped and beat Nichols show how the squad’s work could, and did, go very wrong.Stories of botched work by special law enforcement units are notably common in the U.S. In Baltimore, members of a gun-tracing task force robbed residents of cash, drugs and jewelry. By the time federal officials investigated the New Orleans Police Department in 2010, residents perceived its special units as corrupt and brutal. In Los Angeles, a “special investigation section” in the 1990s was involved in multiple deadly shootouts. There are many more examples.Police departments establish these squads with a good intention: addressing a genuine crime problem. But they fall short in the implementation — tainted by poor leadership, the wrong benchmarks or a culture of impunity.Today’s newsletter will explain how Scorpion, which officials in Memphis disbanded last week, fit into a broader pattern in American law enforcement of well-intentioned efforts to fight crime instead leading to abuses.A sound ideaThe Memphis Police Department founded the Scorpion unit in late 2021 to do what officials call “hot-spot” policing.For regular readers of this newsletter, the term may sound familiar. The idea is to focus police resources on high-crime neighborhoods or city blocks or even people (such as repeat offenders). They can also zero in on specific crimes, like shootings or drug trafficking.The term is broad, and over time just about every big-city police department in the U.S. has said it is focusing on hot spots in some way. When done correctly, the strategy reduces crime without simply displacing it to other areas, studies have found.But those three words are the catch: when done correctly. “When people use the term ‘hot-spot policing,’ that could mean lots of different things,” said Anna Harvey, a public safety researcher at New York University.Many departments ignore important tenets of the concept, sometimes resulting in abuses. For example, the Louisville, Ky., police unit that investigated Breonna Taylor’s ex-boyfriend was also following a hot-spot model. (Officers shot Taylor to death in her home in 2020.)In some hot-spot efforts, police officers merely try to make their presence known — to produce a kind of scarecrow effect, as people are less likely to commit crimes in front of an officer. In others, officers aggressively enforce the law with as many stops and arrests as possible. Exemplary hot-spot policing demands a balancing act between maximizing the deterrence of officers’ presence and minimizing the social costs of hassling, stopping and arresting more people.“You can do hot-spot policing in a way that’s super aggressive, or you can do it in a way that’s more respectful,” said Neil Gross, a sociologist at Colby College who studies the police.Flawed implementationSo what went wrong in Memphis? Officials appeared to emphasize the wrong things, experts said.Police officials deployed Scorpion to the city’s most volatile neighborhoods — “hot spots” — to crack down on all sorts of crimes, like reckless driving or shootings, with punitive tactics even against minor offenses.City officials praised Scorpion for high arrest numbers, effectively encouraging aggressive tactics. Chief Cerelyn Davis lauded the approach, advocating “being tough on tough people.” (Officials could have emphasized other goals, like reductions in crime rates in specific neighborhoods, to help focus officers on results instead of antagonistic methods, experts said.)“It’s the command staff implementing a version of hot-spot policing that is not consistent with what the research evidence says is best,” Harvey said.The unit also seemed captured by a culture of impunity. Consider that at least some of the officers who beat Nichols were wearing cameras that were recording their actions. The fact that they punched and kicked Nichols anyway suggests that they thought they were above the law and could get away with it, said Richard Rosenfeld, a criminologist at the University of Missouri-St. Louis.It is a common phenomenon among American police departments: Evidence-based policies can fall apart in their implementation. Researchers can call for law enforcement strategies that focus on specific places and people and try to minimize the social costs. But if those ideas are filtered through a culture or leadership style that prizes toughness and aggressive action, they can lead to abuse.More Tyre Nichols newsFour officers charged in Nichols’s death had been disciplined before, including two who hadn’t reported using force during arrests, records show.Nichols’s family and the broader community will mourn him at his funeral today.THE LATEST NEWSPoliticsFlorida’s governor, Ron DeSantis.Scott McIntyre for The New York TimesGov.
