Testimony is Evidence

[Ravenshire]

Indeed they can. Which is why it's usually best to get as many pieces as possible. It's just that testimony alone is never enough.

Really I cited a couple of pages (each containing multiple pages) of lawyers who disagree with you.  You may also want to look up on historical method, which discusses testimony as evidence quite a bit.

However, I'm less concerned with you repeating your claim, as I am more concerned with why or your reasoning.

And it's been pointed out to you, with a link to the article, that jurisdictions are starting to caution jurists about witness testimony. Historic precedent isn't holding up well in the reality beyond your delusions.
