Do all latent print development techniques destroy potential biological evidence?

The assertion that not all latent print development techniques destroy potential biological evidence is accurate because different techniques have varied impacts on the evidence they come into contact with. Some development methods, such as powders or certain chemical processes, may have minimal or no impact on biological materials, allowing for the preservation of other types of evidence, such as blood or other bodily fluids.

On the other hand, certain techniques, like cyanoacrylate fuming, can potentially affect biological evidence more adversely. As such, it is critical for investigators to assess the specific technique being utilized and its compatibility with any biological evidence present at a crime scene. Therefore, understanding these nuances helps ensure that both latent prints and biological evidence can be preserved and assessed appropriately without compromising the integrity of either type of evidence.
