I have not been following events in Somalia for several years.
I'm reading a definitive book on the private provision of law, courts,
police, and national security: Anarchy and the Law by Edward Stringham
(ed.). It contains chapters on theory, history, and case studies in private
property anarchy. For example, the free market provision of security in
Ireland (700-1600), Iceland (900-1200), and the U.S. West (1830-1900) are
described in great detail.
Whether you favor or reject the notion advocated by the authors presented in
the book, I highly recommend it for anyone who wishes to consider this topic
from an informed perspective.
