I spent a good four hours last reading reading through the 120-page affidavit from FBI Special Agent Robert H. Root. That affidavit is what convinced a judge there was enough evidence for a search warrant at Pilot. And holy cow, was there some damning evidence. And this is just the beginning.
Anyway, you can read the entire affidavit over here if you want to, but if you just want the juicest parts, scroll on down.
