How come the only terror plot arrests are those the FBI is directly involved in manufacturing? Because that's how they come about in truth--Entrapment

There was "no chance" the scheme could succeed because the FBI was completely involved and in control in setting up the entire operation!

This is the pattern of the Sears Tower arrests too. This article goes on to tell about other "alleged plot" arrests how the "Islamic extremists" who are "suicidal" are pleading "not guilty" (jihadists?) and allege they were set up:

The men had claimed they were set up by an unscrupulous [ed. read FBI] informant.

The pattern by the FBI in this story is very similar to their role in the first 1993 WTC bombing (here).

It is necessary to "terrorize" Americans in order to accomplish the radical agenda that began under Clinton, accelerated under Bush, and continues under Obama.

Updated. Here is a good article from The Nation: Yet Another Bogus "Terror Plot":

The four losers were ensnared by a creepy FBI agent....a confidential informant for the F.B.I. He began showing up at the mosque in Newburgh around 2007....The stranger's [FBI informant's] behavior aroused the imam's suspicions. He invited other worshipers to meals, and spoke of violence and jihad, so the imam said he steered clear of him.
...Members "believed he was a government agent."

...the informant offered at least one of them a substantial amount of money to join his "team."
