Testimony is Evidence

[Thumpalumpacus]

You do acknowledge that we accept witness testimony (sometimes on it own) every minute of every day right? Because the way you go on an on about this implies that the idea is irrational, and by extension, every legal system in the world is irrational.

When the claim is inconsequential, testimony may be valid. When the claim is of consequence, then testimonial suffers accordingly, because it cannot carry such weight. I wouldn't try building a multistoried building on a spongy foundation, either.

The claim that I stayed in bed this morning could be true or false, but it's unimportant in and of itself. If I claim I stayed in bed and therefore could not have committed the murder I am accused of, then my claim merits much more scrutiny due to the gravity of the situation. Taking my word for it at that point would be foolish.
