Eyewitness testimony. DNA. Fingerprints. Police lineups.

Most of us assume these forms of evidence are reliable and objective. After all, we've spent decades watching courtroom dramas where forensic evidence solves every case.

But the reality is far more complicated.

In this episode of Closing Arguments, criminal defense attorney John Razumich examines one of the most misunderstood aspects of the criminal justice system: why evidence isn't always as conclusive as it appears.

John explains how eyewitness testimony can be influenced by stress, memory, and perception, why police lineups must be carefully conducted, and how cross-racial identification has become an important topic in wrongful conviction research. The conversation also explores the so-called "CSI Effect" and why jurors often expect fingerprints, DNA, and other forensic evidence in every criminal case—even though that's rarely how real investigations unfold.

If you've ever wondered how someone could be wrongly identified or why the strongest-looking evidence sometimes turns out to be flawed, this episode offers a fascinating look behind the curtain of the criminal justice system.

Because sometimes, the biggest challenge isn't finding the evidence—it's understanding what the evidence is actually telling us.
