An independent news reporter sued the popular Web site YouTube for copyright infringement, claiming the video file sharing service encouraged users to copy his protected materials.

Robert Tur, a journalist who gained fame with his helicopter-based coverage of the 1992 Los Angeles riots and 1994 freeway chase of O.J. Simpson, filed the lawsuit Friday in U.S. District Court alleging his copyrighted footage had been posted and circulated on YouTube without his permission.
