Well now we have seen at least 34 cases tainted by evidence tampering by the Baltimore cops:

Maryland prosecutors have tossed 34 criminal cases and are re-examining dozens more in the aftermath of recent revelations that a Baltimore police officer accidentally recorded himself planting drugs in a trash-strewn alley.

Baltimore State’s Attorney Marilyn Mosby said that, in all, 123 cases are under review in the wake of a scandal in which one officer has been suspended and two others put on administrative duty. Body cam footage revealed nearly two weeks ago showed one of the officers planting drugs when he didn’t realize his body cam was recording. The Baltimore Police Department’s body cams, like many across the nation, capture footage 30 seconds before an officer presses the record button. The footage was turned over to defense attorneys as part of a drug prosecution—and that’s when the misdeed was uncovered.

Mosby added that the authorities are likely to dismiss many more cases, and they have reviewed hundreds of body cam videos. At least one other is suspicious, she said.

The real question is how common this sort of behavior really is.

My guess is that this is just the tip of the proverbial iceberg.
