Mr Fletcher gave the jury a demonstration of loading the magazine with the bullets. He commented that in his experience loading a full magazine would leave marks on the hands adding "in this case you get a black discolouration". (Transcript PMS/10 page 18B).
When he was cross-examined by Mr Lawson, junior counsel for the appellant at trial, he was asked about this part of his evidence and said (Transcript PMS/10 page 47H):
"Well they are my own observations, and I think the observations of the court yesterday when the demonstration was made, that by loading cartridges into the magazine you get residues on your hands from the bullets and cartridges."
