Kill a cyclist, get community punishment

I think that depends on where they are in terms of their addiction.

It might also be important to factor in whether their addiction was part of their death- the chap on the bike was just that- a chap on a bike who got hit by a car.

Or if the victim ran ice cream vans should jurors also do that?

The point is that as soon as one starts to select juries other than randomly, huge issues an arise. The question is juries or no juries and currently the answer is juries.
