No matter what they tell us, sitting back and waiting for the government to take care of it, isn't how it's supposed to work. In a thousand situations, the fact that "nobody got involved" proves that Chivalry, and Honor are dead. Our principles of "Non-violence" enable us to become castrated wimps, while we have deferred to the dangerous principles found in philosophies such as "Calvinism", which have remove all ethical responsibility from our conscience.
And we aren't really non-violent, thats just our excuse to have enshrined the right of self defense, as opposed to the defense of others. (even the NRA would approve that message) We have embraced self preservation at the expense of the divine imperative. There is a Categorical law. "Do unto others as thou wouldst have them to do for you."
