My immediate thought. The context to that, is that the prosecutors sent a low quality video to the defense, and then late in the trial introduced a high quality video, which the defense couldn't prepare for; and there was a whole argument as to whether it was willful or not. One of the prosecutors claimed the defense's email client might have compressed the video automatically (not how it works), and claimed not to have the knowledge to compress a video, then people started showing screenshots of his personal laptop with Handbrake on the desktop. Now the prosecution is saying this tampering might have happened at the crime lab that sent the compressed video by email to the prosecutors, who forwarded it to the defense, and also gave the full video to the prosecutors on a flash drive.
