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.

As for the ethics, law, and politics relationship, there has always been a tension for me as I try to keep them distinct while recognizing their interactions. A valuable contribution to my thinking there and elsewhere was Ellen Meiksins Wood's Mind and Politics, which reinforced for me the ways in which seemingly disparate philosophical endeavors were/are interconnected, and although I have tended to give a certain priority to ethical considerations as part of practical reasoning, I am reminded often enough that this position makes some contentious presumptions .

Police do not work at the immediate direction of the communities they serve, but through their institutional connections. Police departments may develop structures, modi operandi, and cultures that are ethically problematic.

As a matter of ethics - our broader social life needs to be constrained by law and other devices - resolving at the societal level matters that should not be left for individual ethical negotiation. What is important - in the end - is that we are enabled to flourish in ways that acknowledge our dignity.

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.

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.
