Josh Wolf (pictured), the freelance journalist who was jailed for refusing to give a federal grand jury outtakes of a video he shot of a political protest, walked out of a federal prison in the East Bay city of Dublin this morning (Sept. 1), KCBS-AM reports. A federal grand jury is investigating a 2005 San Francisco protest where a police car was torched and a SFPD officer was injured. The grand jury asked Wolf for video that was not aired on local newscasts and he refused, saying journalists have a right to keep confidential information they receive but decide not to use. Wolf said he suspects prosecutors want him to identify anarchists at the protest. Wolf is free on appeal. Two federal appeals court judges issued a brief ruling Thursday night saying he could be released while his appeal is considered.
