Oded Na’aman describes manning a West Bank checkpoint. Na'aman once let a single crying child pass a closed checkpoint to get home. Ten crying children then approached the closed checkpoint, trying to get through:
The soldier realizes he should not act on empathy since empathy can be manipulated. But can he suppress this natural sentiment? It takes time. The next time a similar situation occurs he does not let the child pass. Instead he smiles at him or tries to make him laugh. These are also signs of weakness. His lenience toward children, if it becomes known, may be used against him. He realizes this when families start encouraging their children to soften him up so they will pass through more quickly. If the harmless Palestinians manipulate him, so can the harmful ones. He makes a further effort to suppress his empathy.
But if sentiments such as empathy are not proper guides for his clear-headed judgment, which are?
Strictly following orders leads to failure as well. He was ordered to use his clear-headed judgment to recognize cases to which the orders do not apply. How should he recognize such cases? Any rule for recognizing exceptions will have to be assigned a higher-order rule by which to recognize its own exceptions. This seems to lead to an infinite regress. The soldier gradually realizes that he cannot but fail his mission: the rules and orders he has to guide him are conditional on his judgment, which cannot be guided by any rule. His judgment is bound to be vacuous.
