Chain-of-custody for evidence from the crime
scene to the court room is a bedrock principle
of both civil and criminal law.Without a clear
and unambiguous chain-of-custody there is no
way to be sure that an object presented to the
court is the same object that was collected at the
scene of the crime.Even evidence presented to
technical experts needs to have chain-of-custody:
without it,there is no way to assure that
the expert’s testimony pertains to evidence from
the actual case that is under consideration
证据从犯罪现场到法庭的监管链是民法与刑法的重要基石.若没有一个清晰的、毫不含糊的监管链,很难保证从犯罪现场提取的证据能原封不动地呈上公堂.提交给刑侦专家的证据,也受监管链的保护；否则,将无法保证刑侦专家针对证据而提交的证词与实际案件有关.
