I have no idea what Kentucky Attorney General Daniel Cameron’s investigation will conclude about Breonna Taylor’s killing at the hands of Louisville police.

But I am sure that demanding the cops essentially be handed over to what amounted to a posse at Cameron’s house, under threats to “burn it down,” is fundamentally un-American and a bastardization of how our justice system is supposed to work.

Local demonstrators, national celebrities and even 10 million signatories to a Change.org petition have criticized Cameron for the Taylor inquiry’s duration, demanding “immediate” charges against the officers involved (often referring to them as “murderers.”) Because they are outraged — not an unjust emotion, mind you — they want Cameron to abandon thoroughness in favor of mob rule.

But if you consider Taylor’s killing a murder, or at a minimum an unjust act requiring some kind of a criminal indictment, what would it serve her memory or our collective desire for an improved justice system for an investigation to be short-circuited because … Beyoncé says so? Or because a public official was threatened by an angry mob on his front lawn?

This is not the justice system — or country — we want, where prominent citizens and angry crowds can influence prosecutors to criminally charge people absent a thorough investigation. That attitude, to the great detriment of African Americans, stained our nation’s past but should not define its future.

The deterioration of faith among African Americans in our criminal justice institutions is justified, and white Americans share their concerns. A Pew Research Center survey, conducted in 2019, found “84% of black adults said that, in dealing with police, blacks are generally treated less fairly than whites; 63% of whites said the same.”

And that was before the national demonstrations sparked by the George Floyd and Taylor killings. This data screams out for a restoration of trust in our institutions. But how can we restore trust if criminal investigations are influenced by external actors and threats of violence?

Diligence takes time. There is no justice to be had without the truth, and no truth without a thorough examination of the facts.

Two writers on these pages opened a recent piece critical of Cameron with the following: “The most important ethical duty of a prosecutor is to serve as the voice for the most vulnerable and underserved groups who cannot speak for themselves.”

A laudable sentiment, but that’s not the job of a prosecutor. According to the National District Attorneys Association, “The prosecutor is an independent administrator of justice. The primary responsibility of a prosecutor is to seek justice, which can only be achieved by the representation and presentation of the truth.”

And in its famous 1935 Berger v. the United States case, the U.S. Supreme Court defined a prosecutor as “the representative not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all; and whose interest, therefore, in a criminal prosecution is not that it shall win a case, but that justice shall be done … while he may strike hard blows, he is not at liberty to strike foul ones.”

What should our expectations be of Kentucky’s attorney general in the Taylor matter? Very simple — obtain the entire truth, no matter what it is, and be as thorough as possible so that justice can be rendered impartially, and that Kentuckians have confidence in the outcome.

To rush such an important matter or charge the officers with crimes unsupported by the facts would indeed strike a foul blow.

Cameron should not be influenced by politics, celebrities or anyone outside the investigation. He should not rush, or stall, based on the demands of those who support the victim or the officers.

Cameron should regard only what is legal and illegal and tune out efforts to influence his investigation via celebrity pressure and personal invective.

Some argue that Cameron is in a no-win situation, facing a decision that is sure to anger this political constituency or that, and perhaps one that will lead to rioting and destruction if you take the demonstrators at their word.

But the glass-half-full view is this: A thorough investigation, no matter how long it takes, in which every piece of evidence and every witness is fully reviewed, could stand as a paragon of how a law enforcement action should be conducted even as we mourn a life taken because of a law enforcement situation gone terribly awry.
