And if they have no information other than these numbskulls having igniters and fusers in the car, and being near a critical military facility? What then? Is it against the law to possess igniters and fusers? Is it against the law to drive on that road?
If that's all they've got, you want the FBI to publicly state that they're terrorists?
A case built on those two facts wouldn't even make it to court.
I'm not saying these guys are pure as the driven snow -- creating fear could be their idea of fun, like that group of Florida ME med students five years back, or it could be a case of intentional in-your-face provocation, like the flying Imams -- but if what the media is reporting are all the facts there are, for the FBI to call this terrorism, as it is defined in our laws, without any further facts, would, as you say, put their credibility in the crapper.
Since that happened I have had this sneaking suspicion that such incidents are part of an orchestrated plan to defeat our security measures by turning our own legal system against our security system. Launch enough law suits and target them broadly enough, and the public as well as the TSA will be more afraid of getting sued (or even arrested) than they will be of allowing suspicious middle easterners on airplanes. We can stop potential hijackers if we have enough eyes watching for the right clues. If the potential hijackers can scare away enough watchful eyes, on the other hand, then their odds of succeeding go way up.
I haven’t decided whether the CAIR people are co-conspirators or just useful idiots.
Excuse me, I seem to have misplaced my tinfoil hat, so I must go . . .
