This is true, and these videos help show that. There are more and more cases being uncovered where the police blatantly lied about their own misconduct in official reports. For instance, the police claimed the the Buffalo protester fell when video shows the police pushed him over, and the police report for the killing of George Floyd made no mention of holding him down by the neck. If there hadn't been video, I doubt either of those two incidents would have been counted in police misconduct statistics.
