"When one spouse is willing to testify against the other in a criminal proceeding — whatever the motivation — their relationship is almost certainly in disrepair; there is probably little in the way of marital harmony for the privilege to preserve. In these circumstances, a rule of evidence that permits an accused to prevent adverse spousal testimony seems far more likely to frustrate justice than to foster family peace."
