I found this recent case harder to swallow: https://www.bbc.co.uk/news/uk-scotland-glasgow-west-49483561

The driver only got 6 years for killing a biker while driving the wrong way down a dual carriageway at night, immediately after snorting 5 lines of coke. He pleaded guilty, so it didn't go to trial. The UK sentence tariff for death by dangerous driving allows for up to 14 years. The fact he was DUI should have seen him get near the maximum sentence.

William McLean got a one-third discount due to an early guilty plea, so the starting point was 9 years rather than six. But I agree it seems to short for something that must be near to the worst example of dangerous driving, with no mitigation from the defence - I would have expected something like 12 years discounted down to 8.

A nice long stretch in solitary confinement should be ideal given his problem interacting with people. He sounds like a really nasty piece of work.

I quite agree with the other comments. Sadly, he doesn't appear to the type to learn his lesson. Harsher sentences required for such individuals, even with guilty pleas. IMHO, time should be ADDED if he misbehaves whilst inside, preferably back up to the maximum permissible sentence length.
