Embedded Player NPR's Julie McCarthy reports from Maidstone, England, on the trial of Dutchman Perry Wacker, the truck driver charged in the deaths of 58 illegal Chinese migrants who suffocated while being smuggled in his truck into Britain. Wacker took the stand yesterday to insist he didn't know he was carrying human cargo. In its cross-examination, the prosecution sought to show he knew full well and closed the vent on his truck to make sure no one heard the illegal migrants inside.
