Low Copy Number DNA Testing Continues to be Questioned (NY Times, ABC News)
In the wake of Marina Stajic’s lawsuit against the NYC OCME, alleging in part that she was forced to retire because of questions she raised about the OCME’s novel low copy number (LCN) DNA testing method, the NY Times Science Section looks into the questionable science. The article explores the problems with LCN testing: “Low copy number DNA analysis can…give incorrect results when it pushes PCR chemistry beyond its limits.” Especially troubling is the use of LCN testing in criminal cases where an error can falsely incriminate a person.

questionable LCN evidence was found inadmissible.
DOJ to review FBI’s forensic science practices “to ensure that experts are not overstating their findings against criminal defendants” (Washington Post)
Deputy Attorney General Sally Yates announced at the annual American Academy of Forensic Sciences conference last week that the Department of Justice will begin to audit testimony from pattern-based FBI forensic science units to examine whether government experts had exaggerated scientific evidence in favor of the prosecution: The DOJ audit of expert testimony comes less than a year after an investigation revealed “at least 90% of trial transcripts [the FBI] analyzed as part of its Microscopic Hair Comparison Analysis Review contained erroneous statements,” and is the first broad government response to the implications of “testimonial overstatements” from forensic science experts.

A new bill that would allow rapid DNA test results into CODIS raises privacy concerns (New Republic)
Rapid DNA devices are portable machines that can render DNA results within two hours. Although proponents of the technology laud its efficiency, rapid DNA tests are expensive and have limited sensitivity. The Department of Homeland Security will begin implementing the new technology “to vet the identity and kinship claims of refugees and immigrants.” Jennifer Lynch, a senior staff attorney at EFF, has argued that the “continued storage of genetic samples from asylum seekers of certain races or ethnicities could leave these overrepresented communities more vulnerable to false matches when the database is searched in the future.”

One point Apple, 0 points FBI: In addition to the San Bernardino matter, the DOJ has ordered Apple to unlock 9 additional cases – all of which are unrelated to terrorism/national security. A big win for Apple out of NY yesterday, when a federal judge ruled in Apple’s favor. Notably, the NY case deals with encryption, which would require less of Apple than the San Bernardino case which requires Apple create an operating system.
