You could also call this flip flopping. It also allows a situation where those who espouse they follow a non-violent philosophy to rationlize killing such as many fundamentalist Christians. Yet the same fundamentalist may claim they absolutely follow the teachings of Jesus.
Using neo-con Bush doctrine, Hamilton College officials would have been in their right to identify those making threats and kill them before they were attacked. Why use logic and consistency when you can rely on situational ethics? Situational ethics frees you from guilt to do whatever you want as long as you can rationalize your actions.

http://en.wikipedia.org/wiki/Situational_ethicsSituational ethics refers to a particular view of ethics, in which absolute standards are considered less important than the requirements of a particular situation. The standards used may, therefore, vary from one situation to another, and may even contradict one another. This view of ethics is similar to moral relativism, and is contradictory to moral universalism, and moral absolutism.
The term situational ethics has been broadened to include numerous situations in which a code of ethics is designed to suit the needs of the situation.
The original situational ethics theory was developed by Joseph Fletcher, an Episcopalian priest, in the 1960s. Based on the concept that the only thing with intrinsic value is Love (specifically agape), Fletcher advocated a number of controversial courses of action.
Opponents are usually moral universalists who view situational ethics, in its purest sense, as inherently contradictory, and argue that the very term "situational ethics" is an oxymoron. They argue that ethics and morality are fundamental and cannot be based on practical, functional, or ethno-centric values; therefore, ethics must be based on something more persistent than one group's assessment of their current situation.
Situated ethics is an entirely different theory in which it is the actual physical, geographical, ecological and infrastructural state one is in, determines one's actions or range of actions - green economics is at least partially based on that view. It too is criticized for lack of a single geographically-neutral point of view from which to apply standards of or by an authority.
