“We have found we can potentially detect an incredibly small quantity of material, as small as one dust-speck-sized particle weighing one trillionth of a gram, on an individual’s clothing or baggage,” Farquar said. “This is important because if a person handles explosives they are likely to have some remaining residue.”
Using a system they call Single-Particle Aerosol Mass Spectrometry, or SPAMS, the Livermore scientists already have developed and tested the technology for detecting chemical and biological agents.
The new research expands SPAMS’ capabilities to include several types of explosives that have been used worldwide in improvised explosive devices and other terrorist attacks.
“SPAMS is a sensitive, specific, potential option for airport and baggage screening,” Farquar said. “The ability of the SPAMS technology to determine the identity of a single particle could be a valuable asset when the target analyte is dangerous in small quantities or has no legal reason for being present in an environment.”
William Trogler and his team at the University of California, San Diego, made a silafluorene-fluorene copolymer to identify nitrogen-containing explosives. It is the first of its kind to act as a switchable sensor with picogram (10-15g) detection limits, and is reported in the Royal Society of Chemistry’s Journal of Materials Chemistry.
Trogler’s polymer can detect explosives at much lower levels than existing systems because it detects particles instead of explosive vapours. In the team’s new method one simply sprays the polymer solution over the test area, let it dry, and shine UV light on it. Spots of explosive quench the fluorescent polymer and turn blue….
Seems obvious to me:
“I reject the notion that Al Qaeda is waiting for ‘the big one’ or holding back an attack,” Sheehan writes. “A terrorist cell capable of attacking doesn’t sit and wait for some more opportune moment. It’s not their style, nor is it in the best interest of their operational security. Delaying an attack gives law enforcement more time to detect a plot or penetrate the organization.”
Terrorism is not about standing armies, mass movements, riots in the streets or even palace coups. It’s about tiny groups that want to make a big bang. So you keep tracking cells and potential cells, and when you find them you destroy them. After Spanish police cornered leading members of the group that attacked trains in Madrid in 2004, they blew themselves up. The threat in Spain declined dramatically.
Indonesia is another case Sheehan and I talked about. Several high-profile associates of bin Laden were nailed there in the two years after 9/11, then sent off to secret CIA prisons for interrogation. The suspects are now at Guantánamo. But suicide bombings continued until police using forensic evidence—pieces of car bombs and pieces of the suicide bombers—tracked down Dr. Azahari bin Husin, “the Demolition Man,” and the little group around him. In a November 2005 shootout the cops killed Dr. Azahari and crushed his cell. After that such attacks in Indonesia stopped.
The drive to obliterate the remaining hives of Al Qaeda training activity along the Afghanistan-Pakistan frontier and those that developed in some corners of Iraq after the U.S. invasion in 2003 needs to continue, says Sheehan. It’s especially important to keep wanna-be jihadists in the West from joining with more experienced fighters who can give them hands-on weapons and explosives training. When left to their own devices, as it were, most homegrown terrorists can’t cut it. For example, on July 7, 2005, four bombers blew themselves up on public transport in London, killing 56 people. Two of those bombers had trained in Pakistan. Another cell tried to do the same thing two weeks later, but its members had less foreign training, or none. All the bombs were duds.

Sir David Omand, who used to head Britain’s version of the National Security Agency and oversaw its entire intelligence establishment from the Cabinet Office earlier this decade, described terrorism as “one corner” of the global security threat posed by weapons proliferation and political instability. That in turn is only one of three major dangers facing the world over the next few years. The others are the deteriorating environment and a meltdown of the global economy. Putting terrorism in perspective, said Sir David, “leads naturally to a risk management approach, which is very different from what we’ve heard from Washington these last few years, which is to ‘eliminate the threat’.”
Yet when I asked the panelists at the forum if Al Qaeda has been overrated, suggesting as Sheehan does that most of its recruits are bunglers, all shook their heads. Nobody wants to say such a thing on the record, in case there’s another attack tomorrow and their remarks get quoted back to them.
That’s part of what makes Sheehan so refreshing. He knows there’s a big risk that he’ll be misinterpreted; he’ll be called soft on terror by ass-covering bureaucrats, breathless reporters and fear-peddling politicians. And yet he charges ahead. He expects another attack sometime, somewhere. He hopes it won’t be made to seem more apocalyptic than it is. “Don’t overhype it, because that’s what Al Qaeda wants you to do. Terrorism is about psychology.” In the meantime, said Sheehan, finishing his fruit juice, “the relentless 24/7 job for people like me is to find and crush those guys.”
I’ve ordered Sheehan’s book, Crush the Cell: How to Defeat Terrorism Without Terrorizing Ourselves.
We finally have some actual information about the “liquid bomb” that was planned by that London group arrested in 2006:
The court heard the bombers intended to use hydrogen peroxide and mix it with a product called Tang, used in soft drinks, to turn it into an explosive.
They intended to carry it on board disguised as 500ml bottles of Oasis or Lucozade by using food dye to recreate the drinks’ distinctive colour.
The detonator would have been disguised as AA 1.5 batteries. The contents of the batteries would have been removed and an electric element such as a lightbulb or wiring would have been inserted.
A disposable camera would have provided a power source.
Any chemists want to take a crack at this one?
Oddly enough, I flew into Orlando Airport on Tuesday night, hours after TSA and police caught Kevin Brown—not the baseball player—with bomb-making equipment in his checked luggage. (Yes, checked luggage. He was bringing it to Jamaica, not planning on blowing up the plane he was on.) Seems like someone trained in behavioral profiling singled him out, probably for stuff like this:
“He was rocking left to right, bouncing up and down … he was there acting crazy,” passenger Jason Doyle said.
But that was a passenger remembering Brown after the fact, so I wouldn’t put too much credence in it.
There are a bunch of articles about Brown and potential motives. Note that he is not an Islamic terrorist; he’s a U.S. Army veteran who served in Iraq:
“This is not him,” she said in a phone interview. “It has to be a mental issue for him. I know if they looked through his medical records…I’m sure they will see…”He’s not a terrorist.”
Brown married Holt’s daughter, Kamishia, 25, about three years ago. They met while serving in the Army and separated a year later. Brown wasn’t the same after returning from Iraq, her daughter told her.
“When he doesn’t take it [medication], he’s off the chain,” Holt said. “When you don’t take it and drink alcohol, it makes it worse.”
Doesn’t sound like a terrorist, but this does:
According to the affidavit, Brown admitted he had the items because he wanted to make pipe bombs in Jamaica. It also indicated he wanted to show friends how to make pipe bombs like he made while in Iraq.
Federal agents said federal agents found two vodka bottles filled with nitro-methane, a highly explosive liquid, as well as galvanized pipes, end caps with holes, BBs, a model-rocket igniter, AA batteries, a lighter and lighter fluid, plus other items used to make pipe bombs and detailed instructions and diagrams. He indicated the items were purchased in Gainesville where he lived at one time.
Ignore the hyperbole; nitromethane is a liquid fuel, not a high explosive. Here’s the whole affidavit, if you want to read it.
Even with all this news, the truth is that we just don’t know what happened. It looks like a great win for behavioral profiling (which, when done well, I think is a good idea) and the TSA. The TSA is certainly pleased. But we’ve seen apparent TSA wins before that turn out to be bogus when the details finally come out. Right now I’m cautiously pleased with the TSA’s performance, and offer them a tentative congratulations, especially for not over-reacting. I read—but can’t find the link now—that only 11 flights were delayed because of the event. The TSA claims that no flights were delayed, and also says that no security checkpoints were closed. Either way, it’s certainly something to congratulate the TSA about.
Props to the writer who came up with the first sentence of the story:
A raw turnip was at the root of a bomb scare that last for hours at a law office.
And a follow-up.
A whole article about a bomb in Times Square without ever mentioning the “t” word.
Along with this, maybe we’re turning a corner. Probably not….
I’d love to get details on this:
A television documentary team said it had made a bomb by mixing a series of odourless and colourless chemicals that could be brought into an aircraft by passengers.
The liquids that were mixed to make the explosive cocktail were all contained in bottles of less than 100ml, which is the limit enforced at most airports around the world at present and was introduced shortly after British authorities thwarted an alleged attempt to blow up transatlantic aircraft in August 2006.
[…]
It blew a gaping hole in a decommissioned aircraft, snapping the ribs of the fuselage.
