As if courts care about any of that. They'll just ask the witness "did you send this email"

[speerer → singpolyma3]

Counter-example: I've used DKIM as evidence in court.

[withinboredom → speerer]

Counter-example example: I've been an expert witness in court to prove an email was a forgery; using DKIM.

[speerer → withinboredom]

It'd be funny if we were working together and just telling the same story behind our aliases.

[withinboredom → speerer]

My case was a family court dispute where one parent forged an email from the other parent about the child's care. It was a pretty wild case. After that, I was pretty convinced some people are just evil.

[cbozeman → withinboredom]

That would be a counter-counterexample, wouldn't it?

[inopinatus → cbozeman]

The stacking of either term is unnecessary, because all counter-examples are also examples, thus:

* an example supporting the counter-example is simply another counter-example, and

* an example contradicting the counter-example is, by definition, also another counter-example.

Corollary: all examples that can be opposed or contradicted by counter-examples are themselves also counter-examples.

[jonas21 → cbozeman]

Nah, it supports the counter-example, so it's a counter-example example.

[singpolyma3 → jonas21]

I'd say it refutes the counter-example. The court doesn't care about DKIM, they care about witness testimony.

DKIM might have convinced the witness sometimes though.

[speerer → singpolyma3]

Courts typically do not care as much about what an expert witness thinks, as rather why they think it - and whether their reasons hold up enough that the conclusions they support should be accepted.

The same is true for breaking into a building. An expensive lock won't protect you against a determined attacker.

[jillyboel → singpolyma3]

Which is why you say "No". Then when they try to prove that you did in fact send it, this comes up.

[qingcharles → jillyboel]

Well, if you did send it then you just perjured yourself, so you better hope you don't get caught :)

[jillyboel → qingcharles]

You'd be lying to the court either way if you did send it and meant to conceal it.
