Isn’t he a journalist?

Joshua Wolf is an American videoblogger who was jailed by a Federal district court on August 1, 2006 for refusing to turn over a collection of videotapes he recorded during a July 2005 demonstration in San Francisco. It included unpublished video footage he shot during a fight on the streets between SF police and anti-G8 protesters. Wolf posted some of the videos on his blog and some clips were aired on TV newscasts that later paid Wolf for the footage. But the Feds are demanding to see everything that wasn’t made public. They allege that the unused portion of Wolf’s video may show the patrol car being set afire. Wolf denies there is an attempted arson in his videotape. He served 226 days in prison at the Federal Correctional Institution in Dublin California, longer than any other journalist in US history has served for protecting source materials. So who qualifies as a journalist and what protection should they receive? Is John Wolf who is mainly a polical videoblogger considered a journalist when he regularly posts videos and commentaries on his blog?
