Police, prosecutors used junk science to decide 911 callers were liars
Junk science is a huge problem in law enforcement.  Treating lie detectors as canonical, the blood splatter analysis to recreate crime scenes, this kind of stuff.It is especially problematic because police orgs are generally pretty good at adopting new techniques. But unfortunately the marketplace of ideas they have to shop in suffers from overrepresentation of garbage products.  A huge part of law enforcement enhancement is going to involve cleaning this market up.
