Final answer:
In perimortem trauma from decapitation, the cuts from sharp objects are usually clean and straight, and should neither be ignored nor altered for accurate forensic analysis.
Step-by-step explanation:
In the context of perimortem trauma, specifically in cases of decapitation involving sharp objects like swords or axes, it's crucial to examine the characteristics of the cut(s). Exploring the forensic evidence, we find that the majority of injuries, around 98.7% to be precise, result from clean cuts to the bone. Given that these cuts often follow a straight line, they manifest the considerable force and precision applied during the striking motion. As perimortem injuries are evaluated for legal or historical analysis, they should neither be ignored nor should one attempt to trim away any jagged or torn tissue as it may alter the forensics of the trauma.
