People charged with crimes often read the police report and assume they are reading the State's case.
They are not.
A police report is an investigator's written account of an investigation.
It may contain observations, witness statements, accusations, conclusions, summaries, and information obtained from other people.
But a criminal trial is not ordinarily conducted by handing the police report to the jury and asking jurors to decide whether they believe it.
The State must prove its case with admissible evidence presented in court.
That distinction can be extremely important.
A Police Report Can Make a Case Look Stronger Than It Really Is
Police reports often read like a complete narrative.
The officer may write that a witness said one thing, another witness confirmed it, physical evidence supported the accusation, and the officer concluded that probable cause existed for an arrest.
On paper, everything can appear to fit neatly together.
Trial can be different.
The defense can ask:
- Who actually witnessed the alleged crime?
- Which witnesses are available to testify?
- What did the officer personally observe?
- Which portions of the report merely repeat what someone else said?
- Are those statements admissible?
- Do recordings actually match the officer's written summary?
- Are there witnesses or facts missing from the report?
Those questions can substantially change the way a case looks.
What Did the Officer Actually See?
Consider an officer who arrives after an alleged assault.
The officer may see a person crying, observe an injury, photograph the scene, interview witnesses, and make an arrest.
Those are matters the officer may be able to describe from personal knowledge.
But if the officer did not witness the assault, the officer ordinarily cannot truthfully testify:
"I saw the defendant commit the assault."
Instead, the officer's conclusion may depend upon what other people told the officer.
That distinction matters.
Witness Statements Inside a Report Create Separate Evidentiary Questions
Suppose a report states:
"The complainant told me the defendant struck her three times."
There are potentially different layers of information involved.
The officer can testify that the officer conducted an investigation.
But if the State wants to prove that the defendant actually struck the complainant three times by introducing what the complainant told the officer, hearsay and confrontation issues may arise.
The fact that an officer wrote the statement into an official report does not automatically make the underlying accusation admissible.
Police Reports Are Not Automatically Admissible Because They Are Government Records
Another misconception is that anything contained in an official government record automatically becomes evidence.
Texas evidentiary law is more complicated.
Rules governing hearsay, public records, business records, authentication, personal knowledge, opinion testimony, and constitutional confrontation can all affect what the jury ultimately hears.
The defense should therefore examine the individual evidence underlying the report instead of treating the report itself as proof of the offense.
Body-Camera Video Can Be More Important Than the Written Report
Modern criminal cases frequently provide something previous generations of lawyers rarely possessed:
a recording of the investigation itself.
Body-camera footage can allow the defense to compare what happened with what was later written.
Sometimes they match closely.
Sometimes they do not.
A report may describe a witness as certain when the recording shows hesitation.
A report may summarize a long conversation in a few sentences.
A report may omit statements favorable to the accused.
A report may fail to mention that another person was present.
A witness may give materially different versions during different portions of the same encounter.
These differences can become powerful areas for cross-examination.
What Is Missing Can Matter
Defense investigation is not limited to examining what police collected.
It also asks what they did not collect.
- Was there surveillance video?
- Were photographs taken?
- Were all witnesses interviewed?
- Were text messages preserved?
- Was a weapon recovered?
- Was forensic testing performed?
- Did officers photograph the location where the event supposedly occurred?
- Did they obtain medical records?
- Did investigators follow up on conflicting accounts?
A police report may tell the story of the investigation that occurred.
It does not necessarily reveal the investigation that could have occurred but did not.
Probable Cause Is Not Proof Beyond a Reasonable Doubt
This is one of the most important distinctions in a criminal case.
Police do not need proof beyond a reasonable doubt before making every arrest.
An arrest may instead be based upon probable cause.
But probable cause is not the standard the State carries at a criminal trial.
To obtain a conviction, the prosecution must prove every element of the charged offense beyond a reasonable doubt.
Therefore, the fact that an officer believed there was probable cause to arrest does not determine whether the State can ultimately prove the accusation to a jury.
An Officer's Opinion Does Not Decide Guilt
Investigators naturally form opinions during investigations.
An officer may believe one witness and disbelieve another.
The officer may conclude that a crime occurred and identify the person the officer believes committed it.
But at trial, guilt is not determined by whether the investigating officer believes the defendant is guilty.
That decision belongs to the factfinder after admissible evidence has been presented and tested through the adversarial process.
The defense can challenge the facts, assumptions, investigative methods, inconsistencies, and evidentiary foundation underlying the officer's conclusions.
Cross-Examination Tests the Investigation
A police report is written by the investigator.
Cross-examination gives the defense an opportunity to examine how that investigation was conducted.
Questions may include:
- What did you personally observe?
- Which facts came from someone else?
- Did you record the interview?
- Did you interview every witness?
- Did you preserve potentially important evidence?
- Did any witness change his or her account?
- Did you investigate information inconsistent with your original theory?
- Did you search for evidence that might support the accused?
- Does your body-camera recording contain information omitted from your report?
Effective cross-examination does not require proving that an officer intentionally did something wrong.
An investigation can be incomplete without being dishonest.
An officer can act in good faith and still reach a conclusion that the evidence does not prove beyond a reasonable doubt.
The Jury Should Decide the Case From Evidence, Not a Written Narrative
Police reports are extremely important to criminal defense attorneys because they reveal how law enforcement understood and documented the investigation.
But they are a starting point for analysis—not the end of it.
A defense lawyer should compare the report against the recordings, photographs, physical evidence, forensic testing, witness statements, medical evidence, dispatch records, and other discovery.
The important question is not simply:
"What does the police report say?"
The better questions are:
"What can the State actually prove?"
and
"What admissible evidence will the jury actually hear?"
Examining the Evidence Behind the Report
At Taylor Defense Firm, we examine the evidence underlying the police narrative rather than assuming that the narrative proves the accusation.
That includes comparing reports with body-camera footage, witness statements, physical evidence, forensic testing, and other available discovery and identifying inconsistencies or missing evidence that may matter at trial.
In a Texas criminal prosecution, an accusation written in a police report is not a conviction.
The State still has to prove the case in court.
