The DA was claiming that his hands were clean, that whatever problem the defense had were not the DA's office fault (although he did blame the crime lab at some point).

His last attempt at claiming clean hands was that he was too technically incompetent to do so maliciously. But that's BS. Even if he doesn't know what handbrake does, if he uses it he's using it to somehow modify it. that's not allowed defense is allowed the exact copy the DA has.

Also, I have a lot of trouble believing that anyone, having used handbrake, hasn't noticed a drop in quality in the video.
