Not according to my dictionary: evidence is a) something that furnishes
proof, b) something legally submitted to a tribunal to ascertain the
truth of a matter. Ian's experiences, while providing an interesting
data-point, fails both of these tests. They clearly show that there is
something wrong with *Ian's* MBP, but to extrapolate this to a claim of
"there is a design flaw in all MBPs" is a sweeping generalization of the
worse kind.

Without wishing to get involved in the particular case of the MSB, I
should point out that you need to get a better dictionary. Not only
does it not differentiate between an item of evidence and a body (i.e.
several items) of evidence, it also simplifies so much that it is
misleading.

An individual piece of evidence *may* furnish proof *sometimes* but in
fact even a whole body of evidence does not always furnish proof.
Consider a trial where many items of evidence are presented that even
taken together may not (in the opinion of the jury) act as proof. Also
bear in mind that it depends on what sort of thing one is trying to
prove.

As expounded by Popper, one observation (i.e. a piece of evidence) may
prove a hypothesis wrong but even many observations may not prove a
hypothesis is correct. e.g. One might have hypothesised that "all
swans are white". For centuries thousands of observations in Europe
would have apparently confirmed that. Then Europeans went to Australia
and seeing just one black swan would prove the hypothesis to be wrong.

A single piece of evidence is only proof of itself. Seeing a white
swan merely proves that the individual swan is white. A fingerprint at
the scene of a crime (i.e. one piece of evidence) merely shows that a
fingerprint was found. Even if another piece of evidence shows that
the print belonged to a particular person it does not prove the person
committed the crime. Indeed, it does not on its own prove the person
was even at the scene of the crime.

Maybe the item with the print was carried there or someone else
transfered the print there to frame the person in question. Just
because one explanation is much more likely than the others does not
*prove* that the most likely explanation is true.

Thus I hope that you can agree that the definition above is so
oversimplified that it is misleading and therefore makes that
dictionary suspect.

That is a wonderful demonstrative (and even poetic?) example. I'll remember
it for future use.

Not originally mine though...
I believe it was first used by Karl Popper.

Still nice, and still appreciated...
