My colleagues and predecessors here at the School of Government have written about video evidence many times over the years, summarizing the basic rules and significant cases in posts available here, here, here, here, and here.
Recently, though, I’ve been getting questions about a relatively new but increasingly common type of video evidence: high-tech, app-controlled, and remotely stored videos taken by automated devices ranging from doorbell cameras to wifi-enabled, cloud-connected, teddy bear spy cams. Do the old rules still work the same way for these new video tools? Is it substantive or illustrative evidence? If it’s substantive, how is it authenticated? Is a lay witness qualified to testify about how these cameras work? Does the proponent need the original video? Come to think of it, what is the “original” of a video that exists only as bits of data floating somewhere in the cloud…?
