A lawyer involved in defending cases bought against people by the RIAA claims that if the music industry wins a crucial case, the future of the Internet may be threatened.
Barker was being defended by Beckerman who made a motion to dismiss the case because the RIAA had forgot to provide any acts or dates or times of copyright infringement as the law normally requires.
The RIAA argued that by merely making files available on the Internet Barker was making a copyright infringement.
Beckerman said that it was a shocking argument because if it were accepted by the court it would probably shut down the entire Internet. If you send any file on the Net the RIAA will be allowed to suspect that you are in breach of copyright.
