David Hardy at Of Arms and the Law has this blog on a report
submitted by Barbara Frey, Special Rapporteur, whatever that is, to the UN Human Rights Councils's Sub-Commission on the Promotion and Protection of Human Rights
"20. Self-defence is a widely recognized, yet legally proscribed, exception to the universal duty to respect the right to life of others. Self-defence is a basis for exemption from criminal responsibility that can be raised by any State agent or non-State actor. Self-defence is sometimes designated as a "right". There is inadequate legal support for such an interpretation. Self-defence is more properly characterized as a means of protecting the right to life and, as such, a basis for avoiding responsibility for violating the rights of another. "
Please read the rest. It is rather disturbing that a HUMAN RIGHTS group would be dithering over the legalistic definitions in international law with regards to a subject that should be more than self-evident.
