Trite meme that ends your otherwise solid comment aside, I suspect I personally would get involved if I knew or suspected criminal wrongdoing from a federal agent, but most cops (like most anyone else) would much rather have a paycheck at the end of the week than feel good about their moral compass.

But I was fired for refusing illegal orders years before ICE started blatantly breaking the law, so my "if I was in those shoes, I would totally do the dangerous but morally correct thing" is almost as worthless as if you said it.

Much like in Eichmann in Jerusalem, even those who actively and knowingly participate in evil deeds are more concerned with getting promoted than stopping to think about the morality of it all.
