I'd almost forgotten about this...now you've gone and got my blood pressure up again. This entire episode was an egregious abuse of power. They damn near ruined this man's reputation, they invaded his home and held his 12 year old daughter and her friend at gunpoint while they ransacked the place, all under the cover of a warrant and acting as agents of the government. Every agent involved in this fiasco should be fired, sued and should face criminal charges. Bast*rds!
I don't pretend to recall all the details a decade later. But if they had a warrant, then in my view the agents are not accountable. Go after the judge.
