9-16-95. NYPaper Page Oner: "Computer Stings Gain Favor As Arrests for Smut Increase." The F.B.I. has plans for its own web to fight computer crimes. As arrests continued in a high-tech drive against the peddling of child pornography on the nation's largest computer network, the Federal authorities said today that they expected to apply the same surveillance techniques to fight many other computer-related crimes, from consumer and securities fraud to money laundering. One way of combating these crimes, they said, will be for Federal agents to go undercover and appear as prey for unwitting criminals. Timothy McNally of the F.B.I.said that while the traditional form of surveillance included activities like waiting in cars and watching suspects for hours, "the playing field has now changed" and now requires agents to become more proficient in using computers to thwart crimes. But some civil liberties experts expressed alarm at the latest surveillance technique, saying it would have a chilling effect on what is now a freewheeling medium. HRT_web (9 kb)
