Lawyers for General Motors came out shooting last week when they finally got their chance to defend against allegations of suborned perjury and obstruction of justice.

Accusing their chief accuser, GM nemesis James E. Butler Jr., of lying about them, GM lawyers also suggested that Butler may have “cooked” critical testimony against GM. But GM’s counsel stopped short of making that accusation outright, saying they would take a higher road than they claim Butler has.
