Suppose a corrupt cop in a small town with one intersection lets his buddies and the city fathers run the one stop light with impunity, but if he doesn't like you, or God forbid, you show up with out of state plates, you're going to get a ticket even if you came to a complete stop.
That does nothing to support the contention that stop lights at intersections are a bad idea. Even the most just, righteous laws can be poorly or abusively enforced. That doesn't mean we need to, or should, do away with them, just the corrupt enforcers.
That seems like the opposite sentiment from that of the Founders’ when drafting the Constitution. They created a system of checks and balances to protect the nation even when corrupt enforcers were in charge. Of course it’s quite easy - just to assume that you can put the right people in charge and everything will turn out ok; but that won’t happen, from time to time corrupt enforcers will find their way into power, which is exactly the time that the theory of limited government is intended to take over and prevent them from causing inordinate damage.
We know that when leftists are in power they’ll do everything in their power to expand the scope of the state. One would hope that when right-wingers had the opportunity they would use their power to limit that scope - you might actually have a level of equilibrium. Leftists come into power and write pages of new, unnecessary laws; rightists come into power rescind them all. If only.
