“Philip was calm and knowledgeable. He gave his evidence confidently and clearly and was not unsettled by probing cross examination. He gave his evidence in a manner which the jury were able to follow and was generally an impressive witness.

I would have no hesitation in recommending Mr Boyce as an expert in the areas of firearms and explosives.”
