Loyalty saves us from the self-advantaging compromising of important relations - such as friendship, marital and professional commitments, group memberships, and so on. But as the Aristotelians would put it, its expression requires phronesis - wisdom not to allow it to compromise other important virtues ,there is something to the ancient doctrine of the unity of the virtues. I believe that is true of all virtues, but especially of the executive virtues - such as industriousness, sincerity, conscientiousness, and courage - which may become detached from substantive goods.

The various roles we incorporate into the criminal justice system as well as the ways in which we construe such roles, lend themselves to the kind of ethical reflection that is open to us all. That said, once we have determined roles and their contours, those who act within them may have special duties and privileges that others may lack. Specific roles may generate ethical inquiries with novel forms, just as new technologies may push us in new directions.

I see ethical considerations as having a certain priority in our interactions - passing judgment on our political and legal processes.

It is odd that a value/virtue that plays such a central role in dramatic literature has played such a small role in philosophical writing. There are probably a number of reasons, but I think that a predilection for a certain kind of individualism is a major one. Others might include the fashionability of consequentialism, the idea that loyalty has more to do with sentiment than reason, as well as its proneness to corruption. The revival of interest in virtue/character as distinct from rules/principles has also created space for a renewed, if hesitant, interest in loyalty.

What we have to ask is this: what can we morally expect of and allow to people whom we deploy to fulfill this or that social role :police officer, school teacher, physician? This may sometimes lead to difficult social decisions - e.g. should police be permitted to illegally import drugs as part of a sting operation? In the end, I think "common - that is, critical - morality" should determine the limits of the police role.

I see loyalty - roughly perseverance in relational commitments despite the cost of such perseverance - as an important human value/virtue. Think of it as a kind of relational glue.

There will always be situations in which conflicts arise between individual and communal values - Catholic police officers deployed to enable women to enter abortion clinics without harassment and doctors who oppose performing abortions. No social role is free of such potential conflicts.
