Well, that’s not what liability means, but your point is well taken. This dissertation sounds like complete BS.
Well I have trouble with big words. After all, liability has five whole syllables. And then I go and do things like presume a dissertation on the study of the applicability of liability would include discussions on the acceptable interpretive limits of truth-telling vis-à-vis the declared focal issue of "defensive" situations, leaping from there to my admittedly indefensible presumption that truth-telling would or could be contrasted with the concept of being responsible or even guilty of "lying." But your point is well taken.
