In a sane, fair, and (crucially) long-term stable system, persons given privilege and authority over others are subject to a higher standard for their own behavior. The long-running US trend of the inverse (additional legal protections for positions of authority) is incredibly destructive. This is a moral and values judgment, yes, but it's not just that -- it communicates to the population at large that they should find their own solutions rather than using the established system.
More succinctly, down this path lie guillotines.
The death penalty should be reserved for people who violate a position of public trust and authority.

The US military is subject to a higher standard, the Uniform Code of Military Justice. Penalties for US service members breaking the law or codes of conduct are much higher and much more severe than civilians. The US military makes routine example of law breakers and misconduct.
The US police force, by contrast, is civilian. They are not licensed, commissioned, or subject to additional standards. Certainly not nationwide standards that would bar police removed from their post from finding similar work elsewhere.
We should pay our police officers more, make them undergo nationally standardized training and licensing, and then hold them to a higher standard if and when they break the law.
Police court-martial.
One of the worst examples in the US is the consequence asymmetry for speech. Law enforcement and federal agents can lie as much as they like with impunity when dealing with citizens, but (a) it's a federal crime to lie to a federal officer (18 US Code § 1001, up to 8 years imprisonment), and (b) truly, anything you say to law enforcement when under any suspicion can and will be used against you in a court of law, even the act of pleading the 5th, regardless of (or perhaps especially because of) your innocence. "I want a lawyer", repeated ad-nauseam, is always the least harmful response, regardless of context[0].
Also, the body of federal law and regulations is so vast that smart people estimate the average person unknowingly breaks roughly 3 federal criminal laws per day[1], giving the federal government the legal ability to arbitrarily arrest anyone they want.
