It's not stupid when you realise that NaN is not "not a number" but rather "not a particular number", this becomes clear from

  hypot(Inf, NaN)
being Inf rather than NaN

That it is humane and morally correct to not follow the rules of justice in some cases, one of those being excessive punishment. I believe that this was the motivation in the subject trial -- I would have acted in the same way. In the UK this is a "perverse verdict", judges and government don't like them, but there's not much they can do about it except restrict trial by jury (which is exactly what the UK government is planning to do).

Thought experiment: You are a juror in a case where a minor is accused of small-time theft, some cans of Coke. There is video evidence, clearly they stole. In the two cases

- the punishment is a small fine

- the punishment is the amputation of both hands

does your verdict depend on the expected punishment?

The usual rules don't apply when terrorism is called: The UK has free speech, except terrorism, the UK has a jury-based rule of law, except terrorism, ... you get the idea.

An interesting comment by Craig Murray on the related Filton case:

This is an extraordinary new legal strategy by which the sentencing for ordinary criminal charges may be radically increased if the judge, and the judge alone, decides there is a terrorist link post verdict. The jury has no say on whether there is a terrorist connection or not, and the judges hide from the jury the possibility of this happening at all.

But the public are not stupid and do not live under a rock. The jury sent a note in the second Filton case to the judge Patrick Field asking him whether there would be sentencing under “terrorist connection”. Field replied to the jury that this was “not your concern”.
