They've got muck; we've got rakes. TPM Muckraker
Sources tell TPMmuckraker that it is indeed possible to understand straightforward questions after having smoked pot. Still, having a stoner for a ringleader doesn't exactly go along with the image of a dangerous, well-coordinated terrorist ring that the FBI and NYPD have tried to present.
After all, Muhammad Atta may have been unable to resist a few drinks and a trip to a Floida strip club just before 9/11, but, after years of intense planning, it's hard to imagine him showing up stoned on the big day.
Frankly, the more we learn about this "plot", the more sketchy and pathetic it seems.
