He's way smarter than them. First off, he knew this raid was going to happen. I assume he has people in the FBI and knows every slimy move they make. I bet those documents are deep underground where they can't get to them. The fed bois were probably given a false lead that they were being stored at his residence, and this raid made them look like shit. My guess is they were all on camera everywhere they went. They went through stuff they had no warrant to look in. No, they're fucked and that raid was a well set trap.
