Why pick on the courthouse for picketing

Last week, this story appeared locally and elsewhere about the war protesters who situated themselves at the W.D. Va. federal courthouse in Abingdon. Evidently, they stopped protesting on Thursday while the NASCAR race fans were coming in and started up again on Saturday when presumably the race people were at the track. There is no comment from anyone who works in the building, which includes the chambers of Judge Widener, Judge Jones, Judge Williams, and Magistrate Judge Sargent.
