She described what she found on arrival: an injured father, a frightened girl, a sergeant recovering from a fall, and several civilians offering accounts that did not match his radio description.
She did not claim to have witnessed the beginning.
Lane asked whether she had undermined a superior in front of civilians.
“I requested medical attention and separated accounts.”
“Did that suggest you doubted him?”
“It suggested the situation needed examination.”
He asked about her initial assumption that Mercer had a valid basis for the detention.
She acknowledged it.
“What changed?”
“The information I received.”
The simplicity of the answer stayed with Isaac.
Changing an assessment when facts changed should have been ordinary. In this case it had required enough resistance to become testimony.
Mercer chose to take the stand.
He described a rapidly developing theft inquiry, a man who questioned instructions, and a girl who entered a dangerous situation despite warnings.
Lane asked about years of service, training, and previous encounters where hesitation created risk.
Mercer spoke confidently.
Then Voss asked which property had been stolen.
“No property was recovered.”
“Which person identified a missing wallet?”
“The call suggested—”
“Which person?”
He admitted there was none.
She played the caller's uncertainty and asked why the report described more certainty than the source contained.
Mercer said the summary shaped his understanding.
She asked why he did not verify before escalating force.
He referred to control of the hands.
The store footage showed Isaac holding a receipt.
Voss did not suggest paper made every possible movement harmless. She asked which specific movement created the threat Mercer claimed.
He described turning, reaching, and tension.
The accounts did not align neatly with the images.
Then she played Leah's recording of his grip on Nia.
“Why did you take her arm?”
“To move her from danger.”
“What danger was she moving toward?”
“The detention.”
“And you then brought her into physical contact with you.”
He said she had already interfered.
Voss asked whether a child saying please and asking about her father required that response.
Lane objected to the characterization. The judge required the question to be tied to the recorded conduct.
Voss did so.
The answer remained unsatisfactory.
The final questions addressed the revisions and the message to Ruiz. Mercer said he wanted a complete account.
Voss displayed the descriptions contradicted by the recordings and asked what completeness meant when a change made the event less accurate.
Mercer looked toward the defense table.
He was not forbidden to explain. He was being required to explain specifically.
Nia was not present for most of his testimony. Serena helped arrange that she could wait elsewhere without feeling excluded from decisions about her own case.
Later, Isaac summarized only what she wanted to know.
“Did he say sorry?”
“No.”
She looked at the floor.
“Did he say what he did?”
“He answered questions. The jury will decide what the answers mean.”
The report history showed when revisions occurred and which descriptions changed. An employee familiar with the records system explained the process rather than leaving jurors to infer significance from colored marks alone.
Some corrections were routine and openly identified. Others changed factual claims after recordings became available. The prosecution had to establish why those differences mattered to the charged allegation, not merely point out that editing existed.
Lane emphasized the legitimate need to clarify reports after a stressful event. Voss agreed in principle and returned to the specific descriptions contradicted by evidence Mercer could access.
The distinction required patience from everyone listening.
Isaac found himself remembering his own first notes, including a crossed-out estimate of how long he lay on the hood. Camille had told him to preserve the correction. An honest change could show the work of becoming more accurate.
Mercer's difficulty was not that he remembered imperfectly. It was the evidence suggesting he used revisions to protect an account the recordings did not support.
Nia asked about the reports that evening in general terms. Isaac explained that changing your mind was allowed and sometimes necessary. Changing a fact because it was inconvenient was different.
She nodded, then asked him to check an answer she had corrected in her homework. The ordinary example made them both smile.
Nia disliked the uncertainty but understood the boundary.
That evening, she asked to walk around the block with him.
They moved slowly, his shoulder aching, her hands deep in the pockets of the jacket.
At the corner, she asked whether they could buy groceries tomorrow.
He said yes before fear could answer for him.
The jury deliberated while Nia attended school.
