It turns out that a whole lot of forensics is more or less bullshit, and that the Justice Department has known this for a long time and not told anyone but prosecutors, even when flawed evidence had put people in prison.

As Radley notes, this is dangerously close to “pitchforks in the streets” stuff:

I mean, think about that. Taxpayer-paid employees of the Justice Department had direct and exclusive knowledge that there may be hundreds of innocent people in prison, they knew that flawed forensics in these cases needed to be reviewed, and their justification for not doing more as these people continued to rot in prison was, Hey, we did the bare minimum required of us by law.
