Most criminal cases do not end with a jury verdict. Some charges are dismissed, while others are resolved through motions, diversion, sentencing agreements, or negotiated pleas. However, every criminal case should still be prepared with the possibility of trial in mind.
Trial preparation can uncover weaknesses in the prosecution’s evidence, expose credibility problems, strengthen pretrial motions, and create leverage during negotiations. When the prosecution knows that the defense is prepared to challenge its case in court, it may evaluate its risks differently.
For someone accused of a crime in Orange County, this makes an attorney’s courtroom experience extremely important. Criminal trials require more than a general understanding of California law. They require the ability to evaluate witnesses, present evidence, cross-examine government experts, respond to unexpected developments, and communicate a persuasive defense to a jury.
At Simmons & Wagner, Scott Simmons and Dan Wagner have more than 56 years of combined experience as former Orange County prosecutors and have tried more than 200 jury cases. Their experience allows them to understand not only how to defend a criminal case, but also how prosecutors prepare a case for trial.
What Happens During a California Criminal Trial?
A criminal trial is the proceeding in which the prosecution attempts to prove the defendant committed the charged offense. The defendant is presumed innocent, and the prosecution carries the burden of proving every required element of the crime beyond a reasonable doubt.
The defense does not have to prove that the defendant is innocent. It may challenge whether the prosecution has presented reliable and legally admissible evidence sufficient to meet its burden.
Although the exact structure depends on the case, a criminal jury trial commonly includes:
- Pretrial motions
- Jury selection
- Opening statements
- The prosecution’s witnesses and evidence
- Defense cross-examination
- A possible defense case
- Rebuttal evidence
- Closing arguments
- Jury instructions
- Jury deliberations
- The verdict
Each stage presents different strategic decisions. An attorney must decide what evidence to challenge, which questions to ask, what information to emphasize, and how to present the defense without unintentionally strengthening the prosecution’s case.
Why Should a Case Be Prepared for Trial From the Beginning?
Trial preparation should not start when the judge sets a trial date. It should begin when the defense first receives the allegations and available evidence.
Early preparation may include reviewing police reports, preserving surveillance footage, interviewing witnesses, examining electronic records, consulting experts, visiting relevant locations, and identifying inconsistencies in the prosecution’s theory.
Waiting too long can place the defense at a disadvantage. Video may be deleted, memories may fade, physical evidence may change, and witnesses may become difficult to locate. A defense team that begins investigating early may be better positioned to preserve information that challenges the government’s account.
Thorough preparation can also reveal that a trial may not be necessary. Evidence uncovered by the defense may support a motion, persuade the prosecution to reduce the charges, improve a plea offer, or demonstrate that the case should not continue.
Preparing for trial does not mean refusing to negotiate. It means making decisions from a position of knowledge rather than assuming that the police reports tell the complete story.
How Does the Prosecution Build a Criminal Case?
The prosecution generally builds its case around the legal elements of the charged offenses. Prosecutors may rely on law enforcement testimony, civilian witnesses, physical evidence, digital records, photographs, video, forensic testing, expert opinions, and statements allegedly made by the defendant.
A prosecutor preparing for trial may ask:
- What must be proven for each charge?
- Which witnesses are necessary?
- Are the witnesses credible and available?
- Is the evidence legally admissible?
- How will the defense challenge the investigation?
- Are there inconsistencies that need to be explained?
- How will the evidence appear to a jury?
- What weaknesses could create reasonable doubt?
Former prosecutors have personally worked through these questions while preparing cases for the government. As defense attorneys, they can apply that insight to identify where the prosecution’s case may be strongest and where it may be vulnerable.
The advantage is not based on special treatment or personal influence. It comes from understanding the government’s decision-making process and anticipating how prosecutors may present their evidence in court.
Why Jury Selection Matters
Jury selection is one of the earliest and most important phases of a criminal trial.
Potential jurors may enter the courtroom with strong feelings about police officers, criminal accusations, certain types of alleged offenses, or the decision not to testify. Some may believe that a person would not have been arrested unless they had done something wrong, even though the law requires the defendant to be presumed innocent.
During jury selection, the attorneys and court ask questions intended to identify potential bias and determine whether jurors can evaluate the evidence fairly.
An experienced trial attorney listens not only to the answers being given but also to how jurors respond. Hesitation, body language, prior experiences, and the way a person discusses law enforcement or criminal allegations may all provide valuable information.
There is no perfect jury. The goal is to identify people who can follow the law, respect the prosecution’s burden, and consider the defense rather than making a decision based on the accusation alone.
The Importance of Cross-Examination
The prosecution presents its witnesses first, and the defense has the opportunity to question them through cross-examination. California Courts identifies cross-examination as the defense’s opportunity to question the witnesses presented by the prosecution.
Effective cross-examination is not simply aggressive questioning. It requires preparation, control, timing, and a clear objective.
A defense attorney may use cross-examination to demonstrate that a witness:
- Could not clearly see or hear what occurred
- Has changed important details
- Has a motive to exaggerate or accuse
- Made assumptions rather than direct observations
- Failed to disclose relevant information
- Cannot reliably identify the defendant
- Was influenced by another witness
- Has an inaccurate memory
- Is contradicted by video, records, or physical evidence
Police officers and expert witnesses may also be cross-examined about their methods, training, assumptions, documentation, or failure to conduct certain investigative steps.
A former prosecutor has experience preparing government witnesses for this process. That perspective can help the defense anticipate how a witness is likely to testify and determine which areas may withstand questioning and which may expose significant weaknesses.
Challenging the Police Investigation
Police reports often form the foundation of the prosecution’s case, but they are not neutral transcripts of everything that happened. A report reflects what the investigating officer observed, was told, considered relevant, and chose to document.
Important information may be missing. Witnesses may have been interviewed together rather than separately. Officers may have failed to preserve video, test physical evidence, photograph injuries, investigate an alibi, or follow up on inconsistent statements.
A defense investigation may examine:
- Whether officers followed proper procedures
- Whether witnesses were asked leading questions
- Whether alternative suspects or explanations were considered
- Whether evidence was properly collected and stored
- Whether a search or seizure was lawful
- Whether statements were obtained legally
- Whether reports accurately reflect recorded footage
- Whether favorable evidence was overlooked
The defense does not have to show that every part of the investigation was flawed. A meaningful failure affecting an important piece of evidence may be enough to weaken the government’s theory or raise reasonable doubt.
Using Expert Witnesses and Forensic Evidence
Some Orange County criminal cases depend heavily on scientific or specialized evidence. This may include DNA testing, toxicology, accident reconstruction, firearm analysis, digital forensics, medical findings, financial records, or psychological evidence.
Expert testimony can appear authoritative to jurors, but expert conclusions are not automatically correct. They may depend on assumptions, incomplete information, disputed methods, or evidence collected under questionable conditions.
An experienced defense team may consult an independent expert to:
- Review the prosecution expert’s methods
- Identify inaccurate assumptions
- Evaluate laboratory procedures
- Examine the chain of custody
- Conduct independent testing
- Explain alternative interpretations
- Help the defense prepare cross-examination
The defense must also decide whether presenting its own expert is strategically beneficial. In some cases, the stronger approach may be to expose the limits of the government’s expert rather than introducing competing testimony.
Does the Defendant Have to Testify?
A defendant has a constitutional right not to testify. The defense is also not required to present witnesses or evidence because the burden remains with the prosecution. California Courts confirms that the defense does not have to present a case, although it may call witnesses or introduce supporting evidence when appropriate.
The decision to testify is highly personal and strategic.
Testifying may allow the defendant to directly explain what happened, challenge an accusation, or provide context that no other witness can offer. However, it also allows the prosecutor to conduct cross-examination.
Before making a recommendation, the defense attorney should consider:
- The defendant’s ability to communicate clearly
- Prior statements about the incident
- Potential impeachment evidence
- The nature of the charges
- Whether other evidence already presents the defense
- How the defendant may respond under pressure
- The risks of prosecution cross-examination
A defendant should never testify simply because they feel they must prove their innocence. The decision should be made after careful preparation and an honest evaluation of the risks and potential benefits.
How Trial Preparation Strengthens Plea Negotiations
Trial experience matters even when a case never reaches a jury.
A prosecutor is more likely to recognize litigation risk when the defense has identified evidentiary problems, interviewed witnesses, prepared motions, consulted experts, and demonstrated an ability to try the case effectively.
An attorney who rarely enters a courtroom may have less leverage when claiming that the defense is prepared for trial. By contrast, an attorney with substantial trial experience can support that position through preparation, detailed analysis, and a history of presenting cases to juries.
Trial preparation may lead the prosecution to reconsider:
- The number or severity of the charges
- Sentencing enhancements
- Whether a felony should be reduced
- The amount of requested custody time
- Whether probation or treatment is appropriate
- The strength of a key witness
- The risk that important evidence will be excluded
- The possibility of an acquittal
No attorney can guarantee that preparing for trial will produce a dismissal or improved offer. However, credible trial readiness can prevent the defense from negotiating solely on the prosecution’s terms.
Why Former Orange County Prosecutors Offer a Distinct Trial Perspective
Former prosecutors understand how the government organizes and presents a criminal case because they have done it themselves.
They know how prosecutors prepare witnesses, respond to defense motions, select evidence, develop themes, address weaknesses, and construct closing arguments. They also understand the pressure points that may cause a prosecutor to reconsider a charge or settlement position.
Scott Simmons completed 118 jury trials and was named Prosecutor of the Year by the Orange County District Attorney’s Office. Dan Wagner worked as a criminal prosecutor for more than 25 years, conducted more than 80 jury trials, and served as head of the Homicide Unit for eight years.
That level of experience is especially valuable when the case involves serious felony charges, disputed forensic evidence, multiple witnesses, expert testimony, or allegations carrying severe sentencing exposure.
Former prosecutors can approach the case with an understanding of both sides:
- What the government must prove
- How the prosecution may organize its evidence
- Which witnesses may be essential
- Where admissibility problems may arise
- How a prosecutor may respond to a particular defense
- What arguments may resonate with a jury
- Which weaknesses may create reasonable doubt
This perspective allows the defense to anticipate rather than simply react.
Choosing an Orange County Criminal Trial Attorney
When evaluating a criminal defense attorney, defendants should ask more than whether the lawyer handles criminal cases.
Important questions may include:
- How many jury trials has the attorney handled?
- Has the attorney tried cases involving similar allegations?
- Does the attorney personally prepare and try the case?
- What experience does the attorney have cross-examining experts?
- How does the attorney investigate evidence beyond the police reports?
- Is the attorney prepared to take the case to trial when necessary?
- How will the attorney explain the risks of trial and available alternatives?
Trial experience does not guarantee an acquittal. Every case depends on its own facts, evidence, legal issues, and circumstances. However, when a client’s freedom and future are at stake, having a lawyer who knows how to operate in the courtroom can make a meaningful difference.
