I interpreted this as "it's shitty to write terrible laws, but even shittier to just blithely enforce them and vaguely acklowledge that they are shitty while doing so".
After all making laws doesn't itself matter in the slightest, what matters is enforcement so enforcing terrible laws is the worse thing.
The implication is that cops may acknowledge that a law is unjust, or flat out unconstitutional, but in the end they don't give a shit and make the invalid "I'm just following orders" excuse to gleefully ruin your life by putting you jail for it anyway.
The phrase is a response to the question "why do you choose to do evil things?" And they think saying they only do it for money is somehow better than saying they agree with it. When it's actually worse

Below is two stills from The Good Place showing Chidi talking to Eleanor. In the first still he is saying "Okay. But that's worse."
In the second still he continues "You do get how that's worse, right?"

His comment is just logical fallacies that move the goalpost. Lawmakers make the laws and cops enforce them. But he wants me to believe voters make the laws and the DA enforces them.
