The preamble to the CAC Ethics Code states, "In carrying out these functions, the criminalist will be guided by those practices and procedures which are generally recognized within the profession to be consistent with a high level of professional ethics. The motives, methods, and actions of the criminalist shall at all times be above reproach, in good taste, and consistent with proper moral conduct." There may be other sections of the ethics code that might be applicable in a specific case (e.g., claiming credit for some work that was done by someone else), but certainly the profession does not consider misrepresentation of credentials as being "consistent with a high level of professional ethics." I think there is an obligation to report to the CAC. The AAFS is not as clear, but could fall under the general heading of misrepresentatio of data.
