On those not quite rare occurrences he usually strikes back with a snide remark or two designed to impugn the reporter's veracity instead of addressing the technical issue, and will escalate the harangue as necessary, usually resorting to ad hominem arguments, in order to kill the messenger. By then, Larkin has often completely derailed the technical argument with the end of it being that his faux pas has been swept under the carpet and, to the unwary observer, dealt with honorably.
