Understanding Evidence in a Criminal Trial

Greg Nelson Attorney at Law Jan. 30, 2024

Facing criminal charges can be a daunting experience, and the intricate nature of a criminal trial can often add to the overwhelming feeling. One of the most crucial aspects to understand during this process is the role of evidence, which often holds significant weight in the courtroom. Evidence, in its various forms, serves as the cornerstone in building a case, and understanding its nuances can be pivotal to the outcome. While the world of evidence and legal proceedings may seem complex, it becomes less intimidating once decrypted and understood. 

As a criminal defense attorney in Omaha, Nebraska, I've spent years navigating the intricacies of criminal trials. One thing I've learned is that the role of evidence is paramount in these proceedings. It's my responsibility to help you understand this vital component of your case. If you are in need of support, reach out to Greg Nelson, Attorney at Law today. I am here for you.  

The Varieties of Evidence

In criminal trials, evidence varies greatly, each type significantly influencing the trial's outcome. Here, we'll dissect the three primary forms of evidence: Direct Evidence, Circumstantial Evidence, and Expert Testimony. Here are some of their unique characteristics and impacts on a case: 

  • Direct Evidence: This is the most clear-cut form of evidence. It substantiates a fact without needing any inference or deduction. Examples could include photographs of you at a certain place, a witness who saw you somewhere, or video footage of you. Owing to its straightforward nature, direct evidence often leaves little room for interpretation and can be highly influential in a case. 

  • Circumstantial Evidence: This type of evidence isn't as obvious as direct evidence and calls for some level of deduction or inference from the jury. The presence of your fingerprints at a crime scene, DNA traces found on an item, or a surveillance video showing you near a crime scene at the relevant time are all instances of circumstantial evidence. While circumstantial evidence may not be as definitive as direct evidence, it can effectively support a case when combined with other forms of evidence. 

  • Expert Testimony: This kind of evidence is offered by professionals with specialized knowledge pertinent to the case. It could be a forensic expert speaking about the significance of DNA analysis or a psychiatrist providing insight into the mental health of the accused. Expert testimonies break down complex scientific or technical data to help the jury understand critical aspects of the case that could potentially sway the verdict. 

Understanding the various types of evidence is critical in any criminal trial. Each form, whether it's direct evidence, circumstantial evidence, or expert testimony, plays a unique role in constructing the case narrative.  

Role of Evidence in Establishing Guilt or Innocence

In a criminal trial, the burden of proof falls squarely on the shoulders of the prosecution. They must present enough evidence to convince the jury beyond a reasonable doubt that the accused is guilty. As your defense attorney, I can challenge the prosecution's evidence and present our own evidence to raise reasonable doubt. 

The jury's role is to carefully evaluate the evidence presented by both sides. They look at factors like the reliability of witnesses, the chain of custody for physical evidence, and the expertise of expert witnesses. Their decision hinges on the totality of the evidence presented. 

It's important to remember that not all evidence is admissible in court. There are legal standards for admissibility, and the judge acts as a gatekeeper to ensure these standards are met. If evidence is obtained illegally or is irrelevant to the case, it may be excluded. 

Examples of Permissible and Impermissible Evidence

In the realm of criminal law, understanding what constitutes permissible and impermissible evidence is crucial. It can significantly impact how a case unwinds in court.  

Permissible Evidence 

Permissible evidence refers to any evidence that can legally and ethically be used in court to support the case:

  • Witness Testimony: Testimonies from reliable witnesses who either directly observed the crime or can provide key information related to the case are admissible. 

  • Physical Evidence: Tangible objects associated with the crime, such as a weapon, a piece of clothing, or a stolen item, may be presented in court. 

  • Expert Testimony: Statements from professionals with specialized knowledge relevant to the case, such as forensic scientists or psychiatrists, are generally permissible. 

  • Documentary Evidence: Records, letters, contracts, or any written document that is relevant to the case can be used as evidence. 

Impermissible Evidence

Impermissible evidence refers to evidence that, for various reasons, cannot be used in court: 

  • Hearsay: This is an out-of-court statement offered to prove the truth of the matter asserted. Hearsay is generally not admissible unless it falls under an established exception. 

  • Illegally Obtained Evidence: Any evidence obtained in violation of a person's constitutional rights, such as evidence seized during an illegal search, is typically inadmissible. 

  • Prejudicial Evidence: If the evidence is more likely to unfairly prejudice the jury against the defendant than it is to prove a point, it may be excluded. 

  • Irrelevant Evidence: Evidence that does not make a material fact more or less probable or is not directly related to the case at hand is considered inadmissible. 

Remember, each case is unique, and what might be permissible in one case could be impermissible in another. Understanding the nuances of evidence admissibility can significantly impact your case's outcome. 

Making Sense of Legal Evidence 

The role of evidence in criminal trials is paramount, acting as the foundation upon which cases are built and verdicts are determined. With variances from direct to circumstantial, to expert testimony, each type of evidence contributes uniquely to a case's narrative.
