Let's Get Philosophical RE: Self-Defense

I think it well past the time when we should be educated (In non-academic terms) as to:
1. What "Natural Law" is;
2. What the Natural Law of self-defense and defense of
innocent others is; And,
3. Why having the ready means of exercising that right is basic
to all human rights---Especially when such "authorities" as
the police are too few and too late (As at Columbine HS and
Virgina Tech) or never take effective actions (As the UN in
the Darfur region of the Sudan).

This is specially important when so many innocents are now being attacked or threatened by "crazies", common criminals and international terrorists (eg Jihadi)
