Abstract
This article raises a principled objection to the privatization of certain core police
services. Whereas most of the literature critical of privatizing security services has
focused on the negative consequences of doing so (corruption, waste, etc.), the argument
here focuses squarely on the standing of private parties to perform police services.
According to an important strain of liberal political theory, certain tasks are assigned
to the state not because it is deemed to be more efficient at delivering those services but
simply because such services must be rendered by a party that acts in the name of the
polity as a whole and not in the name of some narrower private interest. The author
argues that all those policing functions – such as arrest, search, and detention – that
require criminal law justification (because they involve conduct on the part of officers
that is generally criminally prohibited) are of this nature. The article also summarizes
the different dimensions of the larger privatization debate and traces the development
of the debate about legitimate policing in the nineteenth and twentieth centuries.
