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.

Think of loyalty as a kind of relational glue.

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.

Police have both extra constraints and extra permissions - on the one hand, they can't dodge involvement in social disorder as the rest of us can and they may be required to conduct themselves privately in a way that does not undermine their public authority; on the other hand, they have permission to engage in deceptions, invasions of privacy and uses of force that are forbidden to the rest of us. But this does not put them beyond common morality.

My mother thought my inclinations would do well in Law, but I was too shy and deliberative - slowfooted - for that, so I determined to be an English and German high school teacher. In my first year of university I had one subject to "fill in" and chose philosophy against the advice of my counselor. My university teachers in English and German were totally uninspiring; philosophy was wonderful and my results showed it. I chose it and basically backed into a situation in which only a philosophy career seemed a viable option. I've never regretted it, but there was a lot of serendipity.

I grew up in a home in which loyalty to family was central to my father's outlook. Adolescent changes to my outlook (which set me against parental values) made me very critical of loyalty, reinforced by certain religious writers I found influential at that time. Harry Blamires, The Christian Mind. But I remained conflicted about loyalty.

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.
