What is the first step in preserving evidence integrity?

The first step in preserving evidence integrity is enforcing proper collection techniques. This is crucial because any mismanagement in how evidence is collected can lead to contamination, loss, or degradation of the evidence, ultimately compromising its reliability. Proper collection techniques involve using the right tools, wearing gloves to avoid forensic contamination, and following established protocols to ensure that evidence remains in its original state as much as possible. Without this foundational step, no further actions taken—such as photographing the scene or clearing it—can guarantee that the evidence will stand up under scrutiny. Ensuring that evidence is collected correctly sets the stage for all subsequent investigation and legal proceedings.
