One strength is real world crimes of obedience. Research shows that some people disobey legitimate authority as shown in Rank and Jacobson's study. Nurses disobeyed a doctor's order to give an excessive drug dose. The doctor had legitimacy of authority as they are higher in the hierarchy than nurses. However, soldiers at My LAi obeyed their commanding officer which may have been because he had more power to punish them. Therefore, there is some evidence in real world situations that respect for legitimate authority can lead to destructive obedience.
