Evidence in a trial is the backbone of the prosecution's case. It is also usually the backbone of the defense's case. Much of the evidence that is used in criminal trial is scientific evidence or forensic evidence. Both of these play a crucial role in the criminal justice system.
Why is scientific evidence important?
Scientific evidence is important because it is evidence that has been proven through the use of the scientific method. Often, this type of evidence is based on information published in peer-reviewed journals. It is important to note that not all scientific evidence is admissible in all cases. With that in mind, it is crucial that you understand what evidence is permissible and why. There might be instances in which you can call the admissibility into question during your trial.
Why is forensic evidence important?
First, it is important to note that some forensic evidence can also be classified as scientific evidence. This includes some evidence that is commonly used in criminal trials, such as fingerprint evidence and DNA evidence. This type of evidence is often used to tie a person to the crime that is being tried. Even with forensic evidence, it is often possible to challenge the evidence or the procedure used to collect and process the evidence.
If you are facing a criminal trial, such as a drug trial, that hinges on scientific or forensic evidence, you should make sure that you understand how that evidence can be used in trial. This allows you to determine how to address each piece of evidence presented in your case.
