". . . nor indeed is there any certain proof that it was these
head injuries which caused the death of the deceased. You
may think it is; you may well be satisfied beyond reasonable
doubt that it was, but it is not mathematically proved.
Indeed, the accused's story involves, on one possible
interpretation,
that the injuries were done after death because,
as I have already explained to you more than once, the
accused's defence is that either somebody else killed him with
those injuries or he died as a result 'of my stoning him' and
somebody inflicted those injuries after death.
Now there is no certainty about this at all. It is for you
to decide; not as a matter of probability - do not think it is
a question of one story being more probable than another;
the question always is: are you satisfied beyond reasonable
doubt, looking at all the evidence?
Now the rock: the Crown case is that the accused battered
the head of the deceased with some very large object. It may
well be that this object, say the Crown, was the rock of which
we have heard so much, which is in the photographs. They
say this is supported by the fact that blood was found on the
rock and this blood could have been the blood of the deceased.
It is consistent with this rock having drawn blood from the
deceased, or at any rate, the deceased's blood being on the rock.
Once again, there is no certainty. It is another circumstance
which you consider in relation to all the other circumstances.
What is certain is that the blood on the rock was not the
accused's, because it was group O whereas the accused's was
group A.
If you wish me to do so at some later stage I will read to
you the evidence about the placing of the rock and the views
of Dr. Tucker. For what it is worth I do not think I need read
you that evidence now unless you ask me to, but all that the
Crown case suggests is that this rock could have been the rock
which was used by the accused.
You heard Dr. Bromwich's evidence that such a rock dropped
from a distance of anything between a foot and ten feet, and
obviously anything more, would cause the massive injuries
described, at any rate as a matter of probability, assuming
that the head of the deceased was up against something hard
on the other side.
You have also the accused's answers to Mr. McMahon in
which he said, 'Yes, that could have been the rock'. You
will accept, as certainly I do, that he could not have thrown
it with one hand, and in particular lying down.
Even if it had been - and you will probably accept what
Dr. Bromwich says - even if it had been thrown in the way
that a shot-put is done in athletics it is unlikely perhaps that
it would have brought about the massive damage to the skull
which has been described.
But, of course, it is not crucial to the Crown case that that
rock was used. It is suggested as a possible explanation, but
the Crown case does not stand or fall by that rock. It may
have been some other object." (at p190)
