Puffery as a legal term refers to promotional statements and claims that express subjective rather than objective views, such that no reasonable person would take literally.
Robert KC Johnson reviews Puff Daddy, Mike Nifong's campaign web site where he tries to blow smoke up the deucehole of any Durham voter, who might be living under a rock:
The unusually chatty site contains, among other items, a "conversation with Mike," a statement of the DA’s legal philosophy, and a personal letter to Durham voters. Unintentionally revealing in some areas, outright inaccurate in at least one, the site is most notable for its tendency—which would be comical were Nifong’s misconduct not so grave—to position the district attorney as a bastion of integrity, determined to go above and beyond what state procedural regulations require of him.
In a "conversation with Mike," the district attorney opines, "The shortsighted prosecutor concerns himself only with victory in the courtroom and is willing to take whatever advantage he can, no matter the consequence." I wonder how Nifong would reconcile this statement with his decision to order the Durham Police Department to violate not only its own procedures but all statewide norms, and confine the accuser’s photo ID session to lacrosse players. This decision would seem the action of a "shortsighted prosecutor" concerned "only with victory in the courtroom" and "willing to take whatever advantage he can, no matter the consequence."
