Here Is What Happened When Police STARTED WEARING CAMERAS In Rialto, California

[intaglio]

41. In another thread I pointed out that, for some officers, cameras "break"

From the Albuquerque Journal

Manufacturer can’t say why officer’s lapel camera didn’t record
Albuquerque Police Department officer Jeremy Dear’s lapel video turned on and off numerous times the morning he shot and killed 19-year-old Mary Hawkes, according to a report released by Taser International Inc., which makes the cameras.

But it’s unclear why. The report states that investigators don’t know if Dear powered it off or if the cable disconnected. None of the shooting was recorded, according to the report, despite the fact that the camera was turned on at some points.

Jeremy Dear shot and killed Hawkes in the early morning of April 21. Police said she was a suspected car thief and that she pulled a gun on officers after a short pursuit near Zuni and Wyoming. APD received criticism for the lack of video evidence, and Dear has a history of not recording his encounters with the public, according to his personnel file.

emphasis mine

The excuse given by Deputy Chief William Roseman of Albuquerque PD is that the cables are designed to break. This completely ignores the point that the cable did not break but rather, somehow, disconnected and reconnected.

Then there is the other problem which actually occurred in Ferguson sometimes, entirely by chance of course, the wrong recording is saved

The Day Ferguson Cops Were Caught in a Bloody Lie

/snip

Indisputable evidence of what transpired in the cell might have been provided by a surveillance camera, but it turned out that the VHS video was recorded at 32 times normal speed.

“It was like a blur,” Schottel told The Daily Beast on Wednesday. “You couldn’t see anything.”

The blur proved to be from 12 hours after the incident anyway. The cops had saved the wrong footage after Schottel asked them to preserve it.

Thanks to justiceischeap for the OP where I found this second report
