CSI Houston: How a Texas lab has remade the science of forensics

One of the first crime-lab scandals gave birth to a better way of ensuring the integrity and accuracy of forensic evidence. The Houston Forensic Science Center operates independently of law enforcement agencies, with a large staff of scientists and a healthy budget to correct some of the resource-related flaws of its police-run predecessor. Perhaps its greatest innovation is a system of regularly running blind tests as a quality check, to make sure the staff stays vigilant. The goal is to avoid the kinds of bad science that often contribute to wrongful convictions and other injustices.
