Washington ? Illegally download copyright music from the Internet once, or even twice, and you get a warning. Do it a third time, and your computer gets destroyed.

That’s the suggestion made by the chairman of the Senate Judiciary Committee at a Tuesday hearing on copyright abuse, reflecting a growing frustration in Congress over failure of the technology and entertainment industries to protect copyrights in a digital age.

The surprise statement by Sen. Orrin Hatch, R-Utah, that he favors developing technology to remotely destroy computers used for illegal downloads represents a dramatic escalation in the contentious rhetoric over pirated music.

During a discussion of methods to frustrate computer users who illegally exchange music and movie files over the Internet, Hatch asked technology executives about ways to damage computers involved in such file trading. Legal experts have said any such attack would violate federal anti-hacking laws.

“No one is interested in destroying anyone’s computer,” replied Randy Saaf of MediaDefender Inc., a secretive Los Angeles company that builds technology to deliberately download pirated material very slowly so other users can’t.

“I’m interested,” Hatch interrupted. He said damaging someone’s computer “may be the only way you can teach somebody about copyrights.”

The senator, a composer who earned $18,000 last year in song-writing royalties, acknowledged Congress would have to enact an exemption for copyright owners from liability for damaging computers.

Sen. Patrick Leahy of Vermont, the committee’s senior Democrat, later said the problem was serious but called Hatch’s suggestion too drastic.

“The rights of copyright holders need to be protected, but some Draconian remedies that have been suggested would create more problems than they would solve,” Leahy said.
