My Lords, I cannot speak as eloquently as the speakers we have just heard, but I want to say that this feels so much like law made by press release, and law made to virtue-signal, that I feel incredibly uncomfortable about it.
We want to say to emergency workers that we will protect them if they are at risk, but we know that the emergency worker in this instance, PC Harper, was not the target of the crime; it was not intentional to kill an emergency worker. So I do not see even how this operates as a deterrent, because it is not aimed at people who have put those emergency workers at risk, even though those workers have accidentally been killed in the pursuit of a criminal act that is, I accept, dangerous.
There is an exception, which is that the trial judge can make an alternative sentence in “exceptional circumstances”. But, as has been pointed out, the trial judge can already make an alternative sentence—a full life sentence in some circumstances—so why emphasise it, unless it is a political policy statement? It is not a matter of law; it is a question of saying, “We will be hard”, and it will inevitably lead to great injustice. The fact that 16 and 17 year-olds have been included means that very young people could now have mandatory life sentences for manslaughter, with no discretion, and no discretion encouraged. It is so wrong and brought in for all the wrong reasons.
