It doesn't matter if such person hasn't touched a drop of booze in decades. What matters is what he/she attests to as having happened or NOT HAPPENED years before when he/she was drunk-as-skunk kid ON PURPOSE? Especially if that sober-as-a-judge today iteration of that person is testifying or "recalling" on behalf of a friend? Seriously folks how gullible are you that any such "memories" are true?
