Indeed, over the months that followed, as the targets of the investigation spoke with a sometimes unfocused zeal about waging holy war, the informer, one of two used in the investigation, would tell them that he could get them the sophisticated weapons they wanted. He would accompany them on surveillance missions to military installations, debating the risks, and when the men looked ready to purchase the weapons, it was the informer who seemed to be pushing the idea of buying the deadliest items, startling at least one of the suspects.

One of the informers in the Fort Dix case presents another problem for the Government:

He previously lied to agents in an attempt to protect a friend of his. The Government hopes that it can diffuse this by early disclosure.

Is it enough if the defendants merely discussed vague plans that would not have progressed further but for the informer?
