A Massachusetts crime lab chemist has been sentenced to prison after admitting that she faked the forensic tests that put hundreds of people behind bars. More than 330 prisoners have been released, at least 1,100 cases have been dismissed or not prosecuted because of tainted evidence, and authorities say 40,000 defendants might be affectted. As Nebraskans saw in the case of convicted former Douglas County crime scene investigator David Kofoed, such shortcuts do only one thing: damage the criminal justice system. Honesty and integrity are essential when the state sets out to take away someone’s liberty. Reassuringly, justice eventually caught up in both places.
