I just read the entire Judge,s charge to the jury on this one and the following is Mr Stanley,s account of that gun
"He says that he reached into the vehicle with his left hand to attempt to shut off the vehicle. As he did so, he moved what he then thought was a metal bar but which he now believes was the barrel of the damaged .22"
There is a second reference to the gun from a female in the truck owned by the deceased in reference to the rifle as she testified for the Crown.
"She does not recall a firearm in the vehicle and does not recall the incident where Mr. Cross tried to break into a red half-ton by striking it with a .22 calibre rifle.
