What is a disadvantage of using a point-to-point search method for evidence gathering?

When utilizing a point-to-point search method for evidence gathering, one significant disadvantage is that trace evidence, which often consists of microscopic materials such as hair, fibers, or dust, may be easily overlooked. This search method typically involves a systematic approach where investigators move between points of interest in a linear fashion, focusing on clearly defined areas. While this method is effective for locating larger, visible pieces of evidence, it can become challenging to notice subtle or tiny pieces of trace evidence that require careful and detailed examination.

By concentrating on specific points, the broader, more thorough scrutiny needed to uncover trace evidence may not be sufficiently employed, leading to a potential gap in the overall evidence collection process. This issue highlights the necessity of considering the particular method used during an investigation, ensuring it is suited to the types of evidence most critical to the case.
