Let's see..arresting the wrong people...and police beatings....falsifying arrest reports.
John Heaney was handcuffed face down on the ground when a Denver police officer pulled his head up by the hair and then slammed his face into the pavement.
A videotape of the incident shows Heaney barely moving just before it happened.
But in police records and at court hearings, a handful of officers told a different story of a wildly combative Heaney, who they say started a brawl and then allegedly continued to physically assault officers before he was subdued.
Heaney, 57, had his two front teeth broken in the melee and was charged with second-degree assault on a police officer. He faced three years in prison, until the videotape shot by a witness changed everything.
Now, prosecutors have dismissed all charges against Heaney, and Denver police have launched an internal investigation into the officers' conduct and whether they subsequently lied under oath.
"That tape was new evidence that had not been available to us before last week, and it provides a rather compelling reason to dismiss the charges," said Lynn Kimbrough, spokeswoman for the Denver District Attorney's Office.
