Sure thing! I always want to know if something in one of our explanations isn't clear

Moreover, this is an especially tricky question (you can tell because it's # 22, the trickiest portion of every LR section) so it's important to understand every bit of it if you are aiming for a 170+ LSAT score.
This is a flaw question - asking us to find where the argument is "most vulnerable to criticism." From experience, and from the MLSAT curriculum, we know that flaw questions often relate to the assumption that is being made in an argument, which means a test taker should be particularly attuned to issues related to assumptions: scope, degree, and logic gaps.
To my mind, the logic gap I noticed in the argument was that the author went from a premise about allowing violations to routinely go unpunished to a conclusion that society should never allow violations to go unpunished. The author seemed to assume that there were only two logical possibilities: allowing violations routinely to go unpunished and never allowing violations to go unpunished. But of course there is a middle ground, and this is what (D), the correct answer, gets at. A flaw in the argument is that the author doesn't confront the possibility of a society that occasionally - even just very very rarely - allows a violation to go unpunished. There might be all sorts of good reasons to do so, but the author of this argument ignores this possibility - a logical flaw.
Does that make a little more sense

If not, please let me know!
