The Reporters Committee with 44 media groups filed a brief with the U.S. Supreme Court in support of a man assaulted by police who objected to his recording them using excessive force in an arrest. The Tenth Circuit U.S. Court of Appeals ruled earlier in the case that a reasonable police officer would not know from their training they were violating the Constitutional when they assaulted the man. The brief explains that there were clear precedents applying to situation that should have prevented the assault. (Reporters Committee for Freedom of the Press, August 23, 2021, by Grayson Clary)
EFF provides the federal appellate court precedents for allowing citizens to record the police even though the U.S. Supreme Court has not ruled definitely on the issue.
