If you've ever wondered whether the U.S. Department of Justice has asked Microsoft or Google for your emails, you're probably still wondering. That's because the DOJ often issues gag orders that prevent your email service from letting you know you're under investigation.
In 2015, the Department of Justice initiated an effort to review federal standards for forensic evidence and testimony. The move was in response to FBI revelations that its microscopic hair analysis unit had overstated the scientific certainty of their evidence in over 90 percent of cases the agency reviewed. The FBI's revelations and others have led to serious concerns about the reliability of several common forensic techniques and how analysts are trained to testify about them.
