Rapping the NAP

"The precondition of a civilized society is the barring of physical force from social relationships. ... In a civilized society, force may be used only in retaliation and only against those who initiate its use." Ayn Rand

It all depends on what you can twist to fit retaliation and initiation. Perhaps a conventional mind would consider all lawbreaking to initiate force, even in consensual crimes, just as Rand's followers consider fraud and theft to be initiation. What sorts of retaliation are allowed? Is there any expiration date on a violation, so that what would be retaliation in one case would be initiation in another, though the only difference between them is the amount of time that passed between the initiation and the retaliation?
I am not comfortable claiming that any action that remains within the NAP satisfies morality. I am much more comfortable claiming that anything that violates the NAP, violates morality.
