From the National Law Journal: "High-Tech Evidence: A Lawyer's Friend or Foe?" by Tresa Baldas--
Criminal and civil attorneys alike say that in recent years they have tapped into new sources of electronic data -- from cellular towers, electronic toll booths and auto-location tracking devices -- that make it easier to prosecute crimes and support claims. . . .
Information from cellular towers, for example, is being used to track down kidnapping and murder suspects. E-ZPass and other tollbooth records are being subpoenaed by divorce attorneys to catch cheating spouses, or prove a parent isn't around enough in a custody case. Data from tiny black boxes that monitor a car's movements are being subpoenaed by insurance companies investigating accident claims. And state agencies are using new high-tech software to catch tax scofflaws.
Much of the article is about privacy concerns. While those issues are being debated among the experts, however, you should be asking yourself: Are your seeking the right information in discovery?
