Final answer:
Criminal justice ethics is influenced by social context and personal sense of justice but not directly shaped by the U.S. Constitution, which provides the legal framework.
Step-by-step explanation:
According to Braswell, McCarthy, and McCarthy, criminal justice ethics are shaped by various factors, but the U.S. Constitution is not one of them. Ethics in criminal justice are influenced by the social context within which the criminal justice system operates, as well as personal beliefs about what is just and fair. The personal sense of justice among those in the system and the broader context of criminal justice itself shape ethics in the field. The U.S. Constitution undergirds the legal framework within which criminal justice operates, but it does not shape ethics directly; rather, it establishes the legal context for ethical decision-making.
