THE United States has been narrowly saved from lethal terrorist plots in recent years — or so it has seemed. A would-be suicide bomber was intercepted on his way to the Capitol; a scheme to bomb synagogues and shoot Stinger missiles at military aircraft was developed by men in Newburgh, N.Y.; and a fanciful idea to fly explosive-laden model planes into the Pentagon and the Capitol was hatched in Massachusetts.

But all these dramas were facilitated by the F.B.I., whose undercover agents and informers posed as terrorists offering a dummy missile, fake C-4 explosives, a disarmed suicide vest and rudimentary training. Suspects naïvely played their parts until they were arrested.

Ten years after the attack, an in-depth examination of the case against Ivins by PBS’ “Frontline,” McClatchy Newspapers and ProPublica raises fresh doubts about the government’s evidence and questions whether - despite a $100 million investigation - the real anthrax killer remains on the loose.

The Los Angeles Times examines the staggering sums of money expended on patently absurd domestic “homeland security” projects: $75 billion per year for things such as a Zodiac boat with side-scan sonar to respond to a potential attack on a lake in tiny Keith County, Nebraska, and hundreds of “9-ton BearCat armored vehicles, complete with turret” to guard against things like an attack on DreamWorks in Los Angeles.

The Pentagon will not tell the public what it costs to locate, target and kill a single Taliban soldier because the price-tag is so scandalously high that it makes the Taliban appear to be Super-Soldiers. As set out in this article, the estimated cost to kill each Taliban is as high as $100 million, with a conservative estimate being $50 million.

Defense attorneys say an alleged plot to bomb New York synagogues was hatched and directed by a federal informant. Lawyers for four men from Newburgh have filed a motion to dismiss the terror indictment against them. They said the informant badgered the defendants until they got involved in the plot.

They said the informant chose the targets, supplied fake bombs for the synagogues and a fake missile to shoot down planes. The motion said he also offered to pay the defendants, who attorneys alleged weren’t inclined toward any crime until the informant began recruiting them.
