You know the fix is in when a suspect who shot an unarmed man voluntarily provides four hours of un-cross examined testimony to a grand jury without taking the Fifth.

On August 9, Ferguson, Missouri Police Officer Darren Wilson gunned down 18-year-old African American Michael Brown. Since that fateful day, people across the country have protested against racial profiling, excessive police force, and the failure of the criminal justice system to provide accountability.

The nail in the coffin of “equal justice under law” came on November 24, when the St. Louis County grand jury refused to indict Wilson for any criminal charges in the shooting death of Brown. In a virtually unprecedented move, St. Louis Prosecutor Robert McCulloch in effect deputized the grand jurors to sit as triers of fact as in a jury trial.

In a normal grand jury proceeding, the prosecutor presents evidence for a few days and then asks the grand jurors to return an indictment, which they nearly always do. Of 162,000 federal cases in 2010, grand juries failed to indict in only 11 of them, according the Bureau of Justice Statistics.

The standard of proof for a grand jury to indict is only probable cause to believe the suspect committed a crime. It is not proof beyond a reasonable doubt, which is required for conviction at trial. Yet McCulloch’s team presented testimony and documents to the panel for three months, evidence not subjected to adversarial testing by cross-examination.

Justice Antonin Scalia explained the function of the grand jury in United States v. Williams as follows:

[I]t is the grand jury’s function not “to enquire . . . upon what foundation [the charge may be] denied,” or otherwise to try the suspect’s defenses, but only to examine “upon what foundation [the charge] is made” by the prosecutor. [citations omitted] As a consequence, neither in this country nor in England has the suspect under investigation by the grand jury ever been thought to have a right to testify or to have exculpatory evidence presented.

Every principle Scalia cited was violated in this case. The grand jury was asked to determine whether Wilson acted in self-defense. Wilson was allowed to give four hours of self-serving testimony to the grand jury. And for three months, prosecutors presented both incriminating and exculpatory evidence.

The prosecutor did not ask these grand jurors for an indictment. They were left to sift through the evidence on their own, with no prosecutorial guidance about what to charge. Indeed, the transcripts indicated that prosecutors asked Wilson gentle, leading questions designed to bolster his self-defense claim. For example, a prosecutor told Wilson, “You felt like your life was in jeopardy,” followed by, “And use of deadly force was justified at that point, in your opinion?” But prosecutors rigorously challenged witnesses who contradicted Wilson’s testimony.

As the grand jury is a secret proceeding, with only the grand jurors and the prosecutor present, the grand jurors did not hear any cross-examination of the officer’s testimony, or that of other witnesses (which is customary in an adversarial jury trial). These grand jurors, who were nearing the end of their term, which began in May, knew the drill, since they had sat on several other cases. They knew the prosecutor always asks for indictments. Thus, when the prosecutor handled the Wilson case in a radically different manner, this signaled to the grand jurors that they were not expected to indict. And they did not.

Another unorthodox aspect of this case was McCulloch’s announcement of the grand jury’s decision on national television. Sounding like a defense attorney delivering a closing argument in a jury trial, McCulloch characterized and analyzed the witness testimony in the light most favorable to the officer.

McCulloch has a history of bias in favor of police involved in altercations with black men. But, ignoring the pleas of 7,000 residents in and near Ferguson who signed a petition, McCulloch refused to recuse himself in the Wilson case.

McCulloch had mischaracterized testimony in a 2000 case in which two black men were killed after officers fired 21 shots at them. As in the Wilson case, the reasonableness of the officers’ use of deadly force was critical. In the 2000 case, the officers said the two victims were driving toward them, trying to run them down, and McCulloch claimed that all the witnesses corroborated the officers’ story. A later federal investigation, however, determined that the car was not moving forward, and that only three of the thirteen officers said the car was moving forward.

Likewise, Wilson’s claim that Brown was “charging” at him when the officer fired the fatal shots into the top of Brown’s bowed head was critical to the reasonableness of Wilson’s use of deadly force. When McCulloch announced the grand jury’s decision, he characterized the witnesses who testified that Brown was “charging” the officer as believable, but dismissed the testimony of witnesses who said Brown was surrendering. McCulloch sounded like a defense attorney, not a prosecutor charged with representing “the people,” including Brown.

Wilson fired 12 shots at Brown, six of which struck the teenager. There was a great deal of contradiction among the witnesses, including whether Brown’s hands were up or down when Wilson shot at him. That is precisely why there should have been an indictment and a jury trial. Jurors would hear all of the evidence, subjected to adversarial testing by cross-examination. They would assess the credibility of the witnesses, and determine whether Wilson had committed any crime(s) beyond a reasonable doubt.

After reviewing the transcripts and evidence in the Wilson case, San Francisco Public Defender Jeff Adachi noted:

Dorian Johnson, the key witness who was standing next to Brown during the encounter, provided strong testimony that called into question Wilson’s claim that he was defending his life against a deranged aggressor. Johnson testified that Wilson, enraged that the young men did not obey his order to get on the sidewalk, threw his patrol car into reverse. While Wilson claimed Brown prevented him from opening his door, Johnson testified that the officer smacked them with the door after nearly hitting the pair. Johnson described the ensuing struggle as Wilson attempting to pull Brown through the car window by his neck and shirt, and Brown pulling away. Johnson never saw Brown reach for Wilson’s gun or punch the officer. Johnson testified that he watched a wounded Brown partially raise his hands and say, “I don’t have a gun” before being fatally shot.

Adachi also wrote, “Prosecutors never asked Wilson why he did not attempt to drive away while Brown was allegedly reaching through his vehicle window or to reconcile the contradiction between his claim that Brown punched the left side of his face and the documented injuries which appear on his right side.”

If properly directed, the grand jury may well have indicted Wilson for one of several offenses, including first degree murder, second degree murder, voluntary manslaughter, involuntary manslaughter, assault with a deadly weapon, unlawful discharge of a firearm, and battery. Wilson testified that he was acting in self-defense when he shot Brown. If he were indicted, the jury would assess whether Wilson acted reasonably when he used deadly force against the teenager.

A police officer in Missouri can use deadly force in making an arrest or preventing escape if he reasonably believes it is necessary to effect the arrest and also reasonably believes the person to be arrested has committed or attempted to commit a felony, or may otherwise endanger life or inflict serious physical injury unless arrested without delay. The key word is “reasonably.” The jury would be told to consider whether a deadly weapon was used, how far apart Wilson was from Brown when the former used deadly force, any disparities in the sizes of the two, the crime involved, etc. The evidence was contradictory about the distance between the two during the confrontation, both Wilson and Brown were the same height but Brown was heavier, and the officer contradicted himself about whether he knew that Brown was suspected of committing petty theft for stealing cigarillos (a misdemeanor, not a felony) before the officer stopped him.

In Tennessee v. Garner, the Supreme Court held that an officer cannot arrest an unarmed felony suspect by shooting him dead. If the suspect threatens the officer with a weapon, or there is probable cause to believe he has committed a crime involving the infliction or threatened infliction of serious physical harm, deadly force may be used if necessary to prevent escape. Although there is a dispute about whether Wilson knew that Brown was suspected of stealing cigarillos before stopping him, Brown had likely committed petty theft – a non-violent misdemeanor, not a felony.

Wilson’s testimony raises several questions, listed in a piece by Ezra Klein on Vox: “Why did Michael Brown, an 18-year-old kid headed to college, refuse to move from the middle of the street to the sidewalk? Why would he curse out a police officer? Why would he attack a police officer? Why would he dare a police officer to shoot him? Why would he charge a police officer holding a gun? Why would he put his hand in his waistband while charging, even though he was unarmed?”

In my opinion, McCulloch should have filed charges against Wilson, who would then have had the right to a public preliminary hearing. He could present evidence and cross-examine the witnesses against him. And if it were televised, the viewing public could see that justice is done.

According to Adachi, “Wilson’s description of Brown as a ‘demon’ with superhuman strength and unremitting rage, and his description of the neighborhood as ‘hostile,’ illustrate implicit racial bias that taints use-of-force decisions. These biases surely contribute to the fact that African Americans are 21 times more likely to be shot by police than whites in the US, but the statement’s racial implications remain unexamined.”

Because of the great social implications of cases involving police shootings of people of color, the presumption in these cases should be that prosecutors utilize the public preliminary hearing process instead of the secret grand jury proceeding.

In a unified statement, several civil and human rights organizations recommended an independent and comprehensive federal investigation by the Department of Justice (DOJ). They said the DOJ should also investigate all police killings and reports of the use of excessive force and racial profiling against youth and people of color. And they would require Body-Worn Cameras to record every police-civilian encounter, and increased community oversight of local law enforcement.

Thousands of people in cities throughout the country are protesting the travesty of justice that occurred in Ferguson. But, as the civil and human rights organizations wrote in their statement, “Nothing will be resolved until there is a systemic change throughout this nation in the implicit and explicit bias against people of color and particularly African-American youth who are routinely targeted by law enforcement even within their own communities.”
