We don't have much information as of yet.

Here is what we know:
Earlier in the week the FBI visited at least three people with court orders and collected DNA samples.

At least one individual has been subpoenaed to a San Francisco grand jury hearing on October 14th (we believe that's the correct date).
Again, things are just coming in and we will update as we have more information. Anyone effected by this should PLEASE PLEASE post here. We have to be as public as possible about this harrassment and organize resistance to this (and all) grand juries and other forms of FBI repression.
