Robert Dreyfuss in The Nation:

I've seen this movie before. In this case, the alleged perps -- Onta Williams, James Cromitie, David Williams, and Laguerre Payen -- were losers, ex-cons, drug addicts. Al Qaeda they're not. Without the assistance of the agent who entrapped them, they would never have dreamed of committing political violence, nor would they have had the slightest idea about where to acquire plastic explosives or a Stinger missile. That didn't stop prosecutors from acting as if they'd captured Osama bin Laden himself.

By the now, it's maddeningly familiar. A scary terrorist plot is announced. Then it's revealed that the suspects are a hapless bunch of ne'er-do-wells or run-of-the-mill thugs without the slightest connection to any terrorists at all, never mind to Al Qaeda. Finally, the last piece of the puzzle: the entire plot is revealed to have been cooked up by a scummy government agent-provocateur.

Of course, as has been pointed out, we know that--irrespective of facts--this case will be held up as some great triumph in the War on Terror™, a frighteningly close call thwarted by those (implicitly, in the previous administration) who understood the nature of the threat. Mmmm'kay....

Preying on these losers, none of whom were apparently actual Muslims, the "confidential informant" orchestrated the acquisition of a disabled Stinger missile to shoot down military planes and cooked up a wild scheme about attacking a Jewish center in the Bronx.

It gets even more pathetic:

The only one of the four suspects who appears to have aroused any suspicion was Payen, a Haitian native who attended the Newburgh mosque. Assistant imam Hamid Rashada said his dishevelment and odd behavior disturbed some members, said the assistant imam, Hamid Rashada. When Payen appeared in court, defense attorney Marilyn Reader described him as "intellectually challenged" and on medication for schizophrenia. The Associated Press said that when he was asked if he understood the proceedings, Payen replied: "Sort of."

Despite the pompous statements from Mayor Bloomberg of New York and other politicians, including Representative Peter King, the whole story is bogus. The four losers may have been inclined to violence, and they may have harbored a virulent strain of anti-Semitism. But it seems that the informant whipped up their violent tendencies and their hatred of Jews, cooked up the plot, incited them, arranged their purchase of weapons, and then had them busted. To ensure that it made headlines, the creepy informant claimed to be representing a Pakistani extremist group, Jaish-e Muhammad, a bona fide terrorist organization. He wasn't, of course.
