John Paul Stevens,
Green v. Bock Laundry Machine Company…
“ We recognize that the mandatory admission of all felony convictions on the issue of credibility may in some cases produce unjust and even bizarre results. Evidence that a witness has in the past been convicted of manslaughter by automobile, for example, can have but little relevance to his credibility as a witness in a totally different matter. But if the rule is to be amended to eliminate these possibilities of injustice, it must be done by those who have the authority to amend the rules, the Supreme Court and the Congress. ”
