We’ve seen this picture before. We know how it ends. The cast of characters has changed, but we recognize the plot and where it is headed. The question is the same this time as it was the last: why will morally upstanding people do great harm to other human beings? Luckily, we have some answers from Stanley Milgram and his Obedience Study and Philip Zimbardo and his Stanford Prison Study. I apply both to the mess that occurred in our air ports as hundreds of people were unnecessarily mistreated by our agents of Customs and Border Protection.
