'Net firms collect more data; lawyers, prosecutors are using it

'Net firms collect more data; lawyers, prosecutors are using it - Story at Boing Boing
Snip from a piece by Saul Hansell in today's New York Times:

[Internet] data led directly to a suspect in a school bombing threat; it has also been used by the authorities to track child pornographers and computer intruders, and has become a tool in civil cases on matters from trade secrets to music piracy. In St. Louis, records of a suspect's online searches for maps proved his undoing in a serial-killing case that had gone unsolved for a decade.

In short, just as technology is prompting Internet companies to collect more information and keep it longer than before, prosecutors and civil lawyers are more readily using that information. When it comes to e-mail and Internet service records, "the average citizen would be shocked to find out how adept your average law enforcement officer is at finding information," said Paul Ohm, who recently left the Justice Department's computer crime and intellectual property section.

The issue has come to the fore because of a Justice Department request to four major Internet companies for data about their users' search queries. While America Online, Yahoo and Microsoft complied with the request, Google is resisting it. That case does not involve information that can be linked to individuals, but it has cast new light on what privacy, if any, Internet users can expect for the data trail they leave online.

The answer, in many cases, is clouded by ambiguities in the law that governs electronic communication like telephone calls and e-mail.
