Why is it essential to package liquids separately from other evidence?

Packaging liquids separately from other evidence is crucial to maintain the integrity of the evidence. Liquids can contain substances that might interact with other types of evidence, potentially leading to contamination or degradation. By isolating liquids, investigators can ensure that both the liquid evidence and any other physical evidence remain uncontaminated and retain their original characteristics for analysis. This separation is vital for the forensic process, as it helps preserve each piece of evidence in its most unaltered state, thereby supporting reliable and accurate conclusions during investigations and court proceedings.

The other options touch on various aspects of evidence handling, but they do not capture the primary reason for separating liquid evidence, which is the protection of the integrity of all evidence involved.
