> Tempe police obtained the video from Uber If by "from Uber", you mean they popped the SD card from the Uber-owner car's dashcam, sure. > Uber could have easily altered it before handing it over See my comment from the last time someone had suggested the idea of doctored videos: https://news.ycombinator.com/item?id=16644663
What's the timeframe on the video being handled, given to police, etc. Do the police have the authority to take any video files recorded by a vehicle involved in an auto accident? Is a warrant needed? It's more likely that the police opened an investigation, and as part of the investigation, handed over dashcam footage.

From my own experience, the police will take dashcam video evidence the first chance they get because it's the best data they can get their hands on while on a scene. Source: I had interactions with the police on two separate occasions (once when my dashcam happened to record a car break-in taking place as I was driving into a parking lot, and once when some guy road raged me). On the second occasion, they were reviewing the video less than 15 minutes from the time of the incident and had the whole thing resolved within the hour.
Besides, as I said earlier, Uber itself is making a statement admitting it was at fault, and the NTSB investigation has way more forensic data than the crappy quality dashcam video police released, so I don't see how doctoring the dashcam video would fit into the narrative.
