Wet evidence such as bloodstains, semen, and mud must be _____ before packaging.

Wet evidence such as bloodstains, semen, and mud must be allowed to dry before packaging to preserve the integrity and evidentiary value of the material. When evidence is wet, it can become contaminated or can degrade when placed in packaging that does not allow for airflow. Allowing the evidence to dry ensures that it is properly preserved and prevents the growth of bacteria or mold that could compromise the evidence. This practice is critical in maintaining the quality of the evidence for forensic analysis and in supporting its validity in legal proceedings. Properly handling and preparing evidence is essential for law enforcement to uphold the standards of evidence management.
