If the feds were investigating him, it would be his own dumb fault for flapping his gums on here, and one thing's for sure.... they certainly wouldn't be talking to him about how they know what they know. He wouldn't find that out until he was sitting in federal court. 
Well, he made it pretty clear that the feds contacted him, and that they let him on the secret that someone had reported him. Seems they tossed protocol out the window, and just informed him of their case as soon as they got it.
Then they took his website down for some strange reason. Without proof, that's just amazing they'd shut him down. But it's up now, for some strange reason.
So, in order for Vince's statement to be correct, DEA agents would have had to break every rule in the book, and do it in record time. They would have had to reveal the fact they had confidential sources, illegally shut down his business without reason, then let him turn it back on and assure him that "he's in the clear", within 36 hours of the initial post on a message board.
So, the DEA is now working illegally, very fast, and outside of every rule and precedent....
Or...
Vince is lying and pulling a hoax.
Now. If you had to put money on which case is more likely, where would your money be?
