Videoblogger's protest footage demanded by FBI

Josh Wolf says,

I'm a videoblogger and an independent journalist, and I  frequently cover protests and other civil unrest in San Francisco.

On July 8th, I shot a protest in the Mission during which a cop was injured in the course of an altercation. Later that week I was visited by the FBI and asked to hand over the unedited footage from that night.

After speaking to my lawyer I denied their request. A few months later, in the beginning of February I was subponead to appear before a Federal Grand Jury with the tape. On behalf of my pro-bono attorney's at the San Francisco National Lawyer's Guild (NLG), we have filed numerous motions in an attempt to quash the subpoena and a hearing to decide to quash the subpoena occured this morning. We are still awaiting the results of that hearing.

Link to a post on Josh's blog with video from the press conference. If I'm not mistaken, I believe this post contains some of the disputed footage from the July 8, 2005 protest.
