You're wrong on this (or at very least looking at the issue without nuance). More often than not "just following orders" IS a sufficient defense. Only in the most heinous of acts is it considered insufficient (if that weren't the case there'd be no reason to define what is and is not a "war crime")
Deporting someone, even if you feel it's unjustified, is a far cry from a War Crime.
That's the cogent point. The danger in an officer choosing to enforce the law as he or she sees fit is so great that they aren't excused in doing so unless the act is an atrocity. Because once an officer is selectively enforcing the law they actually become the one making the law.
Since officers of the law aren't elected that's unacceptable.
No, you are personally responsible for your actions even when they aren't "the most heinous of acts". Being sworn to uphold an unjust law means that you have no good alternatives available to you: you can break your word (and perhaps lose your income) or you can perpetrate injustice. In that situation you must choose which is the greater wrong.
But the unjust law doesn't need to rise to the level of genocide or war crime before it becomes a greater wrong than breaking your word. I think murdering a single innocent person is worse than breaking your word, for example. How many unjustified deportations does it take? I don't know.
This is a pretty interesting topic. I'm reminded of the famous trial of Adolf Eichmann in Israel after WW2 and Hannah Arendt's book about the trial, "The Banality of Evil".
Eichmann was responsible for over-seeing the trains that sent Jews to concentration camps. He tried, to no avail, to employ the "just following orders" defense. If anyone is interested, definitely check out Hannah's book.
