I would take a different approach: The source code shouldn't be allowed to testify in the first place. Do whatever you want with the black box but the court should ignore it. What the camera should do is produce a video of the offense and that's the only thing the court should look at. The case where the source matters is the breathalyzer--and in that case it shouldn't matter because the the system is *inherently* seriously flawed by biology: breath alcohol is not a good indication of blood alcohol. The breathalyzer should only be used to figure out who needs to be blood tested, it is not remotely reliable enough for court.
