FBI overstated forensic hair matches in nearly all trials before 2000
I'm constantly amazed at how terrible criminal forensic science seems to be. Everything except DNA matching appears to be no better than voodoo, and even the DNA stuff is tricky. Is there something about this particular field that attracts charlatans and incompetents? Is it purely a motivational problem, wherein the people who pay for these results are more interested in a conviction and don't care if it's right?
