Prosecutors around the US are relying on shady science to convict people of crimes -- and it's terrifying

For the last 15 years, crime investigators have employed a type of sophisticated DNA testing todetermine the source of genetic material,like a hair or skin, recovered at a crime scene.
That testing is the most accurate way to analyse material from a crime scene — especially small or damaged samples.
Despite the availability of this DNA testing, however, the FBI recently revealed that some jurisdictions around the US are still relying on an outdated technique called hair microscopy.
