The murder of George Floyd galvanized the public and led to the largest protests in American history. Even Donald Trump said of the videos of Floyd’s killing, “It doesn't get any more obvious or it doesn't get any worse than that,” presumably referring to the use of force by police. America waited anxiously for the outcome of the murder trial of the former police officer Derek Chauvin. The prosecution’s case was notable for the unusually candid and definitive statements against Chauvin’s actions that were made by senior figures in the Minneapolis Police Department. The New Yorker’s Jelani Cobb covered the trial and says that this testimony sends a message to law enforcement. “There are now circumstances where public scrutiny and public outrage and egregious offenses that come to light can actually generate enough outrage that you actually will not be defended by your fellow-officers,” he tells David Remnick. “It may seem like a low bar. But, given what we’ve seen previously, that’s a pretty astounding development.”
