Relatively recent scientific procedure to determine who the guilty criminal isn’t, as with Guy Paul Morin, who was wrongly convicted of murdering Christine Jessop a decade ago, and David Milgaard, who spent 23 years behind bars for a rape and murder for which the police were too lazy to track down the real pertretrator. DNA evidence is quite reliable in determining that some criminals are convicted simply because the authorities don’t like their intransigence in the face of threats and accusations. The negative side-effect of DNA-evidence usage is the proliferation of bad television docudramas.
