'just doing my job' is totally bullshit.
It is human tendency (and even apes and monkeys manifest this behavior) to lick the shoes of powerful people and to trample an innocent person because it gives us a false impression that we belong to a powerful group, hence we are powerful.
We can kill a thief who steels a few bucks but we will become fan of a scammer who robs millions of dollars from banks using white collar crime. We are doomed to serve.
