It's interesting you should quote 25 years on your question title, emmie. The BBC report says 20 years. But the BBC main news said 25, whilst the local news said 20.
In truth he has been sentenced to 20 years (of which he will serve 10) with an extra five years "on licence".
As for the post about "every notch above or below pH 7, would you have jailed him for 28 years for throwing vinegar over someone? (Vinegar has a pH of approximately 2.5 to 3.0)
That is not to make light of what he did, it was an horrendous crime.
