Why Cross-Examination Can Make or Break a Criminal Case

Cross-examination can make or break a criminal case because it gives the defense a chance to test a prosecution witness’s story, expose inconsistencies, and challenge testimony that may not be reliable. A witness may sound convincing at first, but focused questions can reveal problems with what that person saw, remembered, or previously said. At Amanda Hernandez Law, PLLC, our San Antonio criminal defense lawyer can compare witness statements with police reports, videos, photographs, and other evidence before deciding which weaknesses to address during cross-examination.

Cross-Examination Tests What a Witness Actually Knows

A witness can only testify about certain information, and cross-examination gives the defense a chance to test that testimony. Under Texas Rule of Evidence 611(b), a witness may be cross-examined about relevant issues, including credibility. Also, Rule 611(c) generally allows lawyers to use leading questions when they cross-examine a witness. That rule permits our San Antonio criminal defense attorney to ask direct questions designed to pin down exactly what a witness saw, heard, remembered, or did.

Earlier Statements Can Reveal Problems With a Story

A witness may tell police one version of an event and give different details at trial. Those differences may give the defense a basis to question the witness’s recollection. For example, suppose a witness initially told San Antonio police that a suspect wore a red shirt but later testified that the shirt was blue. The defense could question the witness about the earlier description and whether they may also have remembered other details incorrectly.

Texas Rule of Evidence 613 provides a process for questioning a witness about a prior inconsistent statement. It requires the witness to be given an opportunity to explain or deny the earlier statement before certain extrinsic evidence of that statement may be admitted.

Eyewitness Identifications Can Be Tested

An eyewitness may sincerely believe an identification is correct and still be mistaken. Cross-examination can explore the conditions under which the witness saw the person. Our criminal defense lawyer in San Antonio may ask about lighting, distance, obstructions, how long the witness saw the person, stress, distractions, and whether the witness knew the person beforehand.

For an alleged offense outside a crowded bar, for example, questions about darkness, distance, crowds, and the length of the encounter could give jurors facts to consider when evaluating the reliability of the identification.

Police Officers Can Be Cross-Examined

Police officers who testify are also subject to questioning. Our San Antonio criminal defense lawyer may compare an officer’s testimony with body camera footage, photographs, dispatch records, and the officer’s written report. They may also establish which events the officer personally saw and which details came from another person. A discrepancy doesn’t automatically prove that an officer is lying, but it may give the jury more information for evaluating the testimony.

Missing Evidence Can Raise More Questions

Cross-examination may also reveal that evidence expected to support a witness’s account is missing or conflicts with the testimony. A witness might describe an injury that was not photographed, for instance, or give a timeline that conflicts with video timestamps. Missing evidence doesn’t automatically prove innocence, but the defense can use these gaps to test the prosecution’s account.

Good Cross-Examination Requires Knowing When to Stop

More questions are not always better. Repeating damaging testimony may strengthen it. An unnecessary question could also give a witness an opportunity to explain a contradiction. Effective cross-examination requires careful preparation and focused questions based on the evidence already available.
