Congress' leading proponent of forcing Internet service providers to retain records about their users' activities <A HREF="http://news.zdnet.com/2100-9588_22-6068339.html?tag=zdnn.alert">lashed out at the industry</A> on Wednesday, saying such a federal law will be a "very minor burden" to bear. Rep. Diana DeGette, a Colorado Democrat, said at a House of Representatives hearing that new laws were necessary to thwart child pornographers and other Internet predators. Investigations into illicit behavior have been hampered because data may be routinely deleted in the normal course of business, DeGette and other data retention proponents claim.
