The "CSI Effect" & Unrealistic Expectations of DUI Evidence

From "CSI" to "Law & Order," television dramas have captivated audiences with their high-tech crime labs and seemingly infallible forensic evidence.

However, these fictional portrayals often paint a misleading picture of the real-world complexities and potential pitfalls of scientific evidence, particularly in DUI cases. This phenomenon, known as the "CSI Effect," has created unrealistic expectations about the certainty and reliability of forensic evidence, which can have serious consequences in the courtroom.

At LaCross & Murphy, our Port Orchard, Washington criminal defense lawyers have decades of experience defending people from faulty DUI charges. Lead attorney David LaCross is certified in standardized field sobriety tests and has been trained in the Advanced Detection of DUI, and the processes that crime labs use to test blood. Like the officers who patrol the streets, David knows how these cases work – and he knows just how unrealistically they are portrayed.

Here’s what to know about DUI cases in the real world.

The CSI Effect in DUI Cases

In DUI cases, the CSI Effect can manifest in several ways:

• Juror Expectations: Jurors exposed to fictional portrayals of forensic science may expect definitive, irrefutable evidence, such as perfectly calibrated breathalyzer results or flawless blood tests. However, in reality, these tests are not always foolproof, and results can be influenced by a variety of factors, including human error, device malfunctions, and even medical conditions.
• Prosecutor Overreliance: Prosecutors, aware of jurors' expectations, may overemphasize forensic evidence, even when it's not entirely reliable or conclusive. This can lead to an oversimplified presentation of the case and potentially obscure other relevant factors.
• Defense Challenges: Defense attorneys must grapple with jurors' preconceived notions and work to educate them about the limitations of forensic evidence. This often requires calling expert witnesses to challenge the validity of test results or highlight alternative explanations.

Beyond the CSI Effect: Other Factors in DUI Convictions

While the CSI Effect plays a role in shaping public perception, it's not the sole factor influencing DUI convictions. Other significant issues include:

• Police Officer Bias: Implicit bias and the pressure to meet arrest quotas can lead to wrongful DUI arrests. Officers may focus on certain drivers based on stereotypes or pre-existing biases, potentially overlooking other signs of impairment or alternative explanations for observed behaviors.
• Crime Lab Errors: Faulty lab procedures, contamination of samples, and even outright misconduct have been documented in crime labs across the country. These errors can lead to inaccurate test results and wrongful convictions.
• Overreliance on Subjective Tests: Field sobriety tests, such as the walk-and-turn or one-leg stand, are notoriously subjective and can be influenced by a variety of factors unrelated to intoxication. Relying too heavily on these tests can lead to unfair judgments.

What to Do If You've Been Charged with a DUI

If you've been arrested and charged with a DUI, the most important thing you can do is to exercise your right to remain silent and contact an attorney immediately.

Do not answer any questions or agree to any tests beyond what is legally required in your state.

An experienced DUI defense attorney will be able to investigate the circumstances of your arrest and challenge any evidence that may be inaccurate or unreliable.
