Understand this is covered in the Ch11 "Drill it" of the LR Strategy Guide, but I'm not fully satisfied by the explanation.
I'm having difficulty finding a logical standard by which we can judge option C (their actions are not truly criminal) to be supported that does not also apply to option E (they deserve only a light sentence for their crimes).
Sure, we are not sure what actions meet the threshold of "deserving of a light sentence;" but by the same token we are not sure what actions meet the threshold of being "truly criminal."
I am having difficulty in identifying support for the statement for one that do not also apply equally well to the other.
It could be objected that E assumes that the criminals perceive the actions as "crimes," while option C leaves that open. But the stimulus identifies this criminal population as "embezzlers" or "people convicted of violent crimes," which seemed to me to address this concern by restricting the relevant subset of "criminals" to those who are already facing a sentence.
