Take the following as truth: I understand a joke with a Volpe punch line or a joke about the NYPD's sincere efforts to increase minority recruitment (no kidding, this time they mean it) or to make the many other reforms persistently resisted by both the department and the mayor (I'm serious, this time they really, really mean it).
Then the following statement: "These jokes are well known amongst NYPD police officers who agree that there haven't been significant reforms." is true, false, or inconclusive?
Answer: Inconclusive
