Dateline NBC associate producer Michelle Madigan was heckled and derided as she ran from DefCon, the world's largest computer hackers conference, and raced away in a car. . . . "They sent a moderately attractive young lady with a purse cam whose mission was to first capture someone on film admitting to a felony, which is really not cool, and second to catch a fed on film," said DefCon spokesman "Priest." . . . Madigan's flight was followed by hackers and reporting peers openly disapproving her methods.
