When I first read the headline, I thought that Patrick Fitzgerald was nabbed. The case is still interesting, but with far less possibility of Rovian conspiracy theories:

FBI Agents Raid Work, Home Of Special Counsel’s Bloch - WSJ.com
WASHINGTON — Federal Bureau of Investigation agents raided the Office of Special Counsel here, seizing computers and documents belonging to the agency chief Scott Bloch and staff.

More than a dozen FBI agents served grand jury subpoenas shortly after 10 a.m., shutting down the agency’s computer network and searching its offices, as well as Mr. Bloch’s home. Employees said the searches appeared focused on alleged obstruction of justice by Mr. Bloch during the course of an 2006 inquiry into his conduct in office.

The independent agency, created by Congress in the wake of the Watergate scandal, is charged with protecting federal employees and deciding whether their complaints merit full-scale investigation — a first line of defense against fraud and mismanagement in government. It also enforces a ban on U.S. employees engaging in partisan political activity.

If the Special Counsel had been tipped off the raid was coming, could he have attempted to indict the FBI caseworker with his powers?
