In cases of police using excessive force, video footage has changed the game -- but though cameras can capture when police cross the line, it can also clear officers accused of wrongdoing.
"We've all seen the bad ones, where there are issues with the author's arrest and how that was handled," said Minneapolis Police Chief Tim Dolan. "Very seldom does the public see the good ones."
Though no story of an arrest is truly "good," one that ended well for police is the case of Dawn O'Leary, who was seen struggling and arguing with an officer who called for backup while she hurled racial slurs.
At one point in the video, O'Leary refuses to get up and the officer's frustration is obvious -- but it was about to get worse. Once she was in the back of the squad car, O'Leary accused the officer of rape and biting her breast.
"I want a rape kit," O'Leary told paramedics who arrived by ambulance.
Yet, the video shows absolutely nothing happened.
That's hardly the only case where a false claim was made against an arresting officer. Deundra Roberson claimed officers falsely arrested him for driving after revocation when he was just sitting in a parked van, but squad car footage clearly shows Roberson's van pulling over as police turned down the street.
There's also Andrew Vanscoik's claim that officers yelled and swore at him, threatening to "bury him" and "put a bullet" in his head. Video and witnesses confirmed that story was just another fabrication.
Instead of getting a police-brutality pay day from the city, all three have now been charged with falsely reporting a crime, which is a gross misdemeanor.
O'Leary eventually admitted to lying about the report, saying she has a "problem with black people." She was sentenced to nine days of community service.
