You are correct -- the court case said the surveillance was for a warrant at a later date -- but the U.S. Marshalls did not have a warrant with them, they were to do surveillance only.
The U.S. Marshalls then had the audacity to ask the court for immunity for making a false report, lying to the grand jury and then lying to the court.[all in the court case].
I guess the false report resulted in the FBI actions.
