Structurally I don't see a fundamental difference between what we may reasonably expect of police and doctors - though obviously the fact that doctors are generally pursuing life-saving activities and police may be engaged in life-threatening activities may lead to differences in how we construe the moral limits to their roles.

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.

The selection of topics for intensive research has often been a function of serendipitous opportunity. My forays into philosophy of education were largely in response to the prompting of friends and my dissatisfaction with much of what - at that time - passed for philosophy of education. I cannot honestly say that there has been either continuity or an overarching schema, though I suspect ,or at least hope, that someone who looked at my oeuvre might conclude that there was a philosophically integrated author.

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.

In later years, when I started working in police ethics, I was professionally drawn back to the topic but as well was better able to see two sides to loyalty - its importance for certain central human relations such as friendships, but also its corruptibility in the sense that loyalty could be invoked against other moral constraints: it sometimes function as something of a moral Trojan horse, undermining other moral considerations.

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.

Whistleblowing constitutes a nice test case for the evaluation of loyalty. Loyalty also appears at the intersection of many major philosophical debates: general ones such as those between consequentialism and deontology, reason and feeling, virtue and principle, as well as more specific ones such as nationalism and patriotism, morality and obedience, particularism and universalism.
