"Are you able to say, Doctor Kerr, what of those factors was the primary cause for the loss of self control or the inability to control?.... I think undoubtedly the brain damage, which was quite significant and confirmed on psychological testing, had been present for a long time and it's the brain damage that's responsible for the paranoia, the diminished sense of being able to control yourself and the irritability.
The paranoia, did that have any relationship to the brain damage? .... Yes, the paranoia is really a consequence of the brain damage.
And did the paranoia have any relationship to the carrying of the rifle?.... I think so. I think the paranoia and the brain damage had been present for several years and I think he had felt for quite a few years that he was at risk in a city situation or something could happen to him in which he would have to defend himself.
Doctor Kerr, was Mr. Hurd at that time able to weigh the potential advantages and disadvantages of his behaviour when he committed the offences? .... Well, to some extent I think he was but I think he became overwhelmed by his feeling that he was in mortal danger and the moment had finally come when they had come to get him, sort of thing.
Are you able to say what influenced him to go armed in public on that day? . . . . I think it was a habit that had been established for some years and he felt that he was at risk that if anything happened to his car or if some one took a fancy to having a go at him.
In your opinion, was he able to control his behaviour on the day he committed the offences?.... His behaviour then wasn't completely automatic, it wasn't completely out of control and there was a degree of control in as much as he didn't try, as far as I know, to kill a person. He tried to scare the person and he didn't fire the total magazine or anything like that. There was a sense of restraint present, there was some modification of his behaviour that he could still accept.
Are you able to pass an opinion as to the extent of that self control?....Well, as I say, he wasn't totally out of control and yet he had no ability at that time to assess the situation in sensible or practical terms.
Doctor, are you able to pass an opinion now as to the likelihood of this type of incident recurring?.... I think it's highly unlikely that he would ever behave in this way again, as long as he refrains from the use of alcohol or drugs.
Are you satisfied that he has remained free of those two things you mention since treatment? .... Yes, I am satisfied that he has.
Doctor Kerr, from your knowledge of Hurd, are you able to pass an opinion as to the effect on the prisoner of a term of actual imprisonment? .... I don't think it would make any difference to his subsequent way of conducting himself. I think he is completely convinced on the need for abstinence. I don't think there would be anything to gain by imprisonment."
