Police Report Missing Important Evidence?
Why Tucson Criminal Defense Attorneys Investigate Beyond the Report
If you have been arrested or charged with a crime in Arizona, one of the first things you may want to see is the police report. And once you read it, you may have an immediate reaction:
That isn't the whole story.
Maybe the officer left out something important that you said. Maybe another witness could confirm your version of events. Maybe the report makes it sound as though every piece of evidence pointed toward guilt, even though you know the police learned information that pointed in another direction.
That can be incredibly frustrating. But it also highlights an important part of criminal defense that many people do not understand:
The police report is not the case.
A good criminal defense attorney does more than read the police report and accept the investigation as it was presented. Depending on the case, defense preparation may include reviewing body-camera footage, listening to 911 calls, examining photographs and records, interviewing witnesses, interviewing police officers, comparing different accounts, and investigating information that may never have made it into a written report.
At AJB Law Firm, criminal defense attorney Amanda Bynum represents people accused of crimes in Tucson and throughout Pima County. One of the most important parts of defending a criminal case is determining not just what the police documented—but what actually happened.
Police Reports Do Not Necessarily Contain Everything the Police Learned
Police reports are important evidence, but they are not transcripts of an investigation.
An officer decides what to include, how much detail to provide, how to summarize a witness's statement, and what information seems important at the time. Multiple officers may participate in an investigation, while only some of their activities are reflected in the primary report.
That means there can be a significant difference between:
what police learned during an investigation
and
what ultimately appears in the written reports.
Consider a hypothetical example.
A person accused of a crime gives police an explanation of what happened. During the investigation, an officer speaks with another person who may be able to corroborate part of that explanation. But the officer does not prepare a detailed supplemental report documenting that conversation.
If the defense simply reads the written reports and stops there, potentially valuable information could be overlooked.
That is one reason defense investigation matters.
What If a Witness Supports Your Version of Events?
Corroboration can be extremely important in a criminal case. Imagine that the State alleges that an incident happened one way, while the defendant says something very different happened. At first glance, it might appear to be one person's word against another's.
But what if someone else saw part of the incident?
What if another person heard something relevant?
What if a witness saw what happened immediately before or after the alleged offense?
What if that person gave information to police that was consistent with the defendant's account?
The significance of that information will depend on the circumstances, but the defense attorney needs to know it exists.
And sometimes finding it requires looking beyond the narrative contained in the police report.
Why Would a Criminal Defense Attorney Interview a Police Officer?
People sometimes assume there is no reason for a defense attorney to interview a police officer because the officer already wrote a report.
But a report and an interview serve very different purposes.
An officer interview can allow a defense attorney to ask questions such as:
Who else did you speak with?
What did those people tell you?
Did you take notes?
Did you record the conversation?
Did you prepare a supplemental report?
Did another officer conduct additional follow-up?
Was evidence collected that is not mentioned in the report?
Did you receive information that was consistent with the defendant's account?
Did you investigate that information further?
Why was particular information omitted from your report?
Those questions can reveal information that is difficult—or sometimes impossible—to identify merely by reading the written disclosure.
An officer interview can also help the defense understand the investigation itself.
For example, if an officer received information supporting the defendant's explanation but did not follow up on it, that may raise different issues than a case in which police thoroughly investigated the information and found evidence contradicting it.
The objective is not simply to find mistakes made by police officers. It is to understand what the investigation actually established.
Criminal Discovery in Arizona Is More Than Receiving a Stack of Reports
Arizona criminal cases are governed by discovery rules that require the parties to disclose certain information and evidence.
For the defense, obtaining disclosure is only the beginning.
Depending on the case, disclosure may include or lead to review of:
police reports and supplemental reports;
body-worn camera footage;
photographs;
911 recordings;
dispatch or CAD information;
witness statements;
laboratory and forensic reports;
medical records;
surveillance footage;
digital evidence; and
other materials related to the investigation.
The defense may also seek interviews with witnesses disclosed by the prosecution, including law enforcement witnesses.
Why does that matter?
Because criminal cases often look different when the evidence is examined collectively instead of simply reading the officer's narrative of what occurred.
Body-camera footage may provide additional context. A 911 call may differ from a later statement. A witness may remember details omitted from the report. An officer may describe investigative steps that were never documented.
Each piece of information can help the defense evaluate the strength—and weaknesses—of the State's case.
What Happens When the Defense Cannot Obtain an Officer Interview?
Arizona's criminal discovery rules are intended to allow both sides to prepare for trial. When required discovery obligations are not satisfied, the court has authority to address the problem.
The appropriate remedy depends heavily on what happened and how the violation affects the defense.
In some circumstances, a defense attorney may ask the court to order compliance. In others, the defense may seek sanctions, restrictions on evidence or testimony, or other relief designed to address the prejudice created by the discovery violation.
But there is an important strategic consideration that is easy to miss:
The most severe sanction is not necessarily the best result for the defendant.
Suppose, for example, that a police officer possesses information favorable to the defense.
Preventing that officer from testifying may punish the prosecution for a discovery violation—but it could also deprive the defendant of useful evidence.
Effective criminal defense is not about requesting the harshest possible sanction in every situation. It is about determining what remedy best protects the particular client.
That distinction matters.
When Missing Information Becomes Part of the Defense
Police officers are not legally required to conduct a perfect investigation before someone can be prosecuted. An investigative mistake does not automatically mean a criminal case should be dismissed.
But investigative gaps can still matter.
Suppose police receive evidence supporting the accusation and pursue it aggressively. At the same time, they receive information supporting the defendant's account but fail to document it, preserve it, or investigate it further.
That may become relevant when evaluating how complete and reliable the investigation actually was.
The distinction is especially important because the burden of proof in a criminal case belongs to the State.
The defendant does not have to prove innocence. The prosecution must prove each element of the charged offense beyond a reasonable doubt.
When jurors are asked to rely on a police investigation in deciding whether that burden has been met, meaningful omissions in the investigation can become important—particularly when the missing information relates directly to the defendant's explanation of what happened.
Sometimes the Most Important Question Is: What Didn't the Officer Do?
Criminal defense investigation is often about asking questions that are not answered by the police report.
If a witness identified another person who saw the incident, did police interview that person?
If surveillance cameras were nearby, did anyone attempt to obtain the footage?
If the defendant offered an explanation that could have been independently verified, did anyone try to verify it?
If a witness's account changed, was that change documented?
If an officer spoke with someone who corroborated part of the defendant's account, where is that information reflected in the investigation?
Those questions do not necessarily prove that the defendant is innocent. But they may expose assumptions, gaps, inconsistencies, or missing evidence that should be considered before anyone concludes that the State can prove guilt beyond a reasonable doubt.
Body-Camera Footage Can Tell a Different Story
Body-worn camera footage has also changed the way criminal defense attorneys can evaluate police investigations.
Years ago, an attorney might have had little more than a written report describing an encounter. Today, many cases include video showing what actually happened.
The differences can be significant.
A report might describe someone as uncooperative while the video provides additional context for the interaction. A report may summarize a statement in a sentence even though the actual conversation lasted several minutes. A report may focus on incriminating statements while giving less attention to statements favorable to the accused.
Video does not automatically favor either side. But it provides another source against which the written account can be compared.
That is why careful review matters.
Why Early Investigation Can Be Important
Some evidence does not remain available forever.
Surveillance footage may be overwritten. Witnesses may become difficult to locate. Memories can fade. Businesses close. Phone records may become harder to obtain. Physical evidence can disappear.
Even when the police have already completed their investigation, the defense may need to conduct its own investigation as early as possible.
That does not necessarily mean recreating the entire police investigation. It means identifying the factual issues that matter and determining what evidence could help answer them.
In some cases, the most valuable information is already sitting in the State's disclosure.
In others, it may come from interviewing a witness.
And occasionally, an important fact emerges only because the defense attorney asks an officer a simple question:
What else did you do?
A Criminal Charge Is an Allegation, Not the Final Story
When someone is arrested, the police report often becomes the first organized narrative of what supposedly happened.
It can feel authoritative. It has an officer's name on it. It contains dates, statements, observations, and conclusions. Prosecutors may rely on it when making charging decisions.
But it is still one account of an investigation.
The criminal justice system does not require a defendant to accept that account without scrutiny.
A defense attorney's job includes examining the evidence, identifying inconsistencies, investigating favorable information, challenging unsupported conclusions, and determining whether the State can actually prove the charge beyond a reasonable doubt.
Sometimes that means focusing on what is written in a police report.
Sometimes it means discovering what was left out.
