As Glenn points out, what officials assert in an affidavit is not factual. I’ve sat through enough trials to understand this, but you might not. You really should read the whole thing:

Second, in order not to be found to have entrapped someone into committing a crime, law enforcement agents want to be able to prove that, in the 1992 words of the Supreme Court, the accused was “was independently predisposed to commit the crime for which he was arrested.” To prove that, undercover agents are often careful to stress that the accused has multiple choices, and they then induce him into choosing with his own volition to commit the crime. In this case, that was achieved by the undercover FBI agent’s allegedly advising Mohamud that there were at least five ways he could serve the cause of Islam (including by praying, studying engineering, raising funds to send overseas, or becoming “operational”), and Mohamud replied he wanted to “be operational” by using exploding a bomb (para. 35-37).

But strangely, while all other conversations with Mohamud which the FBI summarizes were (according to the affidavit) recorded by numerous recording devices, this conversation — the crucial one for negating Mohamud’s entrapment defense — was not. That’s because, according to the FBI, the undercover agent “was equipped with audio equipment to record the meeting. However, due to technical problems, the meeting was not recorded” (para. 37).

Thus, we have only the FBI’s word, and only its version, for what was said during this crucial — potentially dispositive — conversation. Also strangely: the original New York Times article on this story described this conversation at some length and reported the fact that “that meeting was not recorded due to a technical difficulty,” but the final version omitted that, instead simply repeating the FBI’s story as though it were fact: “undercover agents in Mr. Mohamud’s case offered him several nonfatal ways to serve his cause, including mere prayer. But he told the agents he wanted to be ‘operational,’ and perhaps execute a car bombing.”

Third, there are ample facts that call into question whether Mohamud’s actions were driven by the FBI’s manipulation and pressure rather than his own predisposition to commit a crime. In June, he attempted to fly to Alaska in order to work on a fishing job he obtained through a friend, but he was on the Government’s no-fly list. That caused the FBI to question him at the airport and then bar him from flying to Alaska, and thus prevented him from earning income with this job (para. 25). Having prevented him from working, the money the FBI then pumped him with — including almost $3,000 in cash for him to rent his own apartment (para. 61) — surely helped make him receptive to their suggestions and influence. And every other step taken to perpetrate this plot — from planning its placement to assembling the materials to constructing the bomb — was all done at the FBI’s behest and with its indispensable support and direction.

It’s impossible to conceive of Mohamud having achieved anything on his own. Before being ensnared by the FBI, the only tangible action he had taken was to write three articles on “fitness and jihad” for the online magazine Jihad Recollections. At least based on what is known, he had no history of violence, no apparent criminal record, had never been to a training camp in Afghanistan, Pakistan or anywhere else, and — before meeting the FBI — had never taken a single step toward harming anyone. Does that sound like some menacing sleeper Terrorist to you?
