Members of the jury, this is an identification case, and because issues of identification are difficult, there's something I want to say about that before I generally summarise the evidence. The state says to you that its witnesses, and this is Nolan, Moffat, Green and Davies, have correctly identified the accused, and the accused says they're mistaken. The law is, members of the jury, that there is a special need for you to be cautious before you convict an accused in reliance upon the correctness of the identification of the accused by witnesses who do not know the accused.
Now, there are very good reasons for that rule. It exists, members of the jury, because there is a special risk that identification evidence may lead to a wrongful conviction. It's the experience of judges and lawyers that mistakes in identification do occur. Those mistakes occur not infrequently, and despite the mistake being honest and the witness being very careful, innocent people have been convicted based on faulty identification.
If a witness honestly believes that their identification of an accused person is correct, that witness can be very convincing when giving evidence even though they may be mistaken, and again that has been the experience of judges and lawyers. It's also our experience that more than one witness can be mistaken in their identification of an accused person.
So, members of the jury, you should examine closely the circumstances in which each witness saw the offender and the circumstances in which that witness later made the identification of the accused. For instance, you will consider how long did the witness see the person who committed the offence for, at what distance and in what light? Were there any obstructions or distractions to the witness's observations? Did the witness see the offender face to face or at an angle? Were there any distinguishing features about the offender that the witness noticed; height, complexion, hair, clothing et cetera, or was there anything unusual or distinctive about the offender's appearance?
You may also consider how long was it between the original observation and the subsequent identification to the police; that's another matter you may wish to consider when assessing the identification evidence. In respect of Ms Green, you will note from the evidence that it was some four weeks between the original observation and subsequent identification, and Ms Davies I think it's about five and a half weeks.
There is no evidence before you that anybody who did a digiboard identification had previously seen the composite picture in The West Australian newspaper which might somehow influence them; but that apart, the other matters to which I have referred might falsely enhance a person's belief in the reliability of their identification.
In this case, members of the jury, you will recall there was photo identification evidence given by Davies and Green. There was no direct evidence as to how the police came to have a photograph of the accused person, Mr Horsman. As I have told you, you must not speculate about matters that are not in evidence. There may be any number of reasons why the police may have a photograph of a person or access to such a photograph and that may be for an entirely innocent purpose so don't speculate about why the police may have had a photograph.
Photo identification evidence does have some limitations and like any other identification evidence has to be examined carefully. A photograph is two-dimensional; it's static, it's limited. It doesn't depict a manner of moving, posture, variety of facial expressions; it doesn't depict often as not complexion, body size, body shape, colouring, nor many of the other subtle characteristics that an actual sighting may convey to the mind.
The danger is that a photograph of a person may resemble the suspect in the recollection of a witness who saw the suspect only once and so lead to a false identification. Members of the jury, you will no doubt ask yourselves whether there were any material discrepancies between the description that the witness gave to the police, and in court, and the accused's actual appearance (ts 289 - 291).
