The decision to bring criminal charges came after prosecutors reviewed the independent recordings and interviewed the witnesses separately. The allegations were not based on Grace's rank, the volume of public outrage, or the fact that a senior military officer had contacted dispatch. They rested on a narrower question: whether a deputy had knowingly used official authority to deprive a person of her rights, despite facts demonstrating that the detention and force were unjustified. Prosecutors believed the evidence could answer that question beyond a reasonable doubt.
A federal grand jury returned an indictment charging Perkins with willfully depriving Grace of her constitutional rights under color of law. State prosecutors considered the physical assault, damage to her uniform and decorations, and the false statements associated with his arrest report. The two offices coordinated so that neither pursued evidence in a manner that compromised the other. Perkins, through counsel, entered a plea of not guilty and said he had acted on a good-faith suspicion.
The phrase good faith became central to his defense. His attorney argued that a public ceremony was a sensitive setting, that law enforcement could investigate possible impersonation, and that the deputy had mistakenly believed Grace's identification was fraudulent. He could point to genuine authority to question suspicious behavior under lawful circumstances. What he could not easily explain was why Perkins had refused repeated offers to confirm her identity and then physically removed insignia before obtaining a single piece of corroborating evidence.
Defense counsel also raised concerns about the attention the case had attracted. The videos had been watched by millions, and clips appeared online with captions that sometimes distorted the chronology. The judge agreed that jurors should be questioned carefully about what they had seen before trial, and that the government would have to prove its case with admissible evidence rather than public opinion. Grace approved of the ruling. A trial that appeared predetermined would serve no one who wanted lasting accountability.
The lead federal prosecutor, Assistant United States Attorney Naomi Mercer, met with Grace in a conference room several weeks before the trial. Mercer was meticulous, with a quiet voice and a habit of leaving long silences after questions. She warned Grace that the defense would examine her memory, her interpretation of Perkins's behavior, and whether she had made statements she did not include in her first interview. It would not be a personal conversation, she said, and Grace should not mistake the questions for an accusation by the government.
"I've testified before," Grace replied. "Not in circumstances like this, but I understand the process."
"There's one thing I want you to keep in mind," Mercer said. "Your military record explains who you are. It does not give you rights other citizens lack. We are going to present the facts in a way that makes that clear."
Grace nodded. She had waited months to hear a prosecutor say that so directly. "That's exactly what I want," she answered. "I don't want the argument to be that he harmed the wrong woman. I want the argument to be that he had no right to harm any woman in that situation."
