“ . . .It is thus clear that the European Court of Human Rights has considered what English law requires for self defence, and has not suggested that there is any incompatibility with Article 2. In truth, if any officer reasonably decides that he must use lethal force, it will inevitably be because it is absolutely necessary to do so. To kill when it is not absolutely necessary to do so is surely to act unreasonably. Thus, the reasonableness test does not in truth differ from the Article 2 test as applied in McCann. ”
“There are two schools of thought: (1) that the judge should stop the case if, in his view, it would be unsafe (alternatively unsafe or unsatisfactory) for the jury to convict; (2) that he should do so only if there is no evidence on which a jury properly directly could properly convict. Although in many cases the question is one of semantics, and though in many cases each test would produce the same result, this is not necessarily so. A balance has to be struck between on the one hand a usurpation by the judge of the jury’s functions and on the other the danger of an unjust conviction.”
