I particularly like this part:
Forensic evidence is not uniquely immune fromthe risk of manipulation. According to a recent study conducted under the auspices of the National Academy ofSciences, “[t]he majority of [laboratories producing foren-sic evidence] are administered by law enforcement agen-cies, such as police departments, where the laboratoryadministrator reports to the head of the agency.” National Research Council of the National Academies, Strengthen-ing Forensic Science in the United States: A Path Forward 6–1 (Prepublication Copy Feb. 2009) (hereinafter NationalAcademy Report). And “[b]ecause forensic scientists often are driven in their work by a need to answer a particularquestion related to the issues of a particular case, theysometimes face pressure to sacrifice appropriate method-ology for the sake of expediency.” Id., at S–17.
We have had this in all of the military labs over time – Drug Labs, USACIL, DCFL. Military labs have not been immune to error and/or manipulation.
