To the majority of your comment, I agree. However, one thing that I want to note, and this is a bit of semantics, but I think very important here:

>Due process was 100% violated in each of these cases.

Your reasoning that due process was violated is that the accused (and the prosecutor) both lied. I'll point out that the reason we have due process in the US is in part to defend against false accusations. As a result, I think that the series of events false accusation -> investigation and case -> acquittal is the opposite of a failure of due process, its a shining success.

This extends to the Roy Moore/project veritas example too, but replace "due process" with "journalistic integrity", and remove the sort abuse of power overtones that make due process that much more important.
