Alot of crominals wear gloves during crime so as not to leave behind prints. What new development would cause thse criminals to be even more careful?

Advancements in forensic science, particularly in the field of touch DNA analysis, would compel criminals to be even more cautious. This technology allows for the extraction and identification of DNA from even the smallest skin cells left on surfaces, making it easier to link suspects to crime scenes. As a result, criminals may opt for additional protective measures, such as using multiple layers of gloves or avoiding direct contact with surfaces altogether, to minimize the risk of leaving behind any trace evidence.
