7/7: What kind of explosives have been used? Endless contradictions.

Why is it so difficult to figure out what kind of explosives were used?

Basically every day we have a new report what kind of explosives were used in the London bombings.
At first it was:
The rapid-fire explosions in London suggest timers were used to detonate the bombs, a technique that also indicates a level of sophistication that goes beyond a makeshift cell of terrorists. Police also said the 10-pound bombs were made of "high explosives," likely plastic explosives, another indication of a sophisticated terror cell at work.
http://www.nydailynews.com/front/story/326743p-279325c.html

Then it is more specific:
A SINGLE bombmaker using high-grade military explosives is believed to be responsible for building the four devices that killed more than 50 people last week, The Times can reveal. (…)
They also believe that the materials used were not home made but sophisticated military explosives, possibly smuggled into Britain from the Balkans.
“The nature of the explosives appears to be military, which is very worrying,” said Superintendent Christophe Chaboud, the chief of the French anti-terrorist police, who was in London to help Scotland Yard.

The explosive used in the London bomb attacks was almost certainly military TNT originating from former Soviet satellite countries, intelligence sources said yesterday.

But the very same day (July 12) el-Nashar’s appartement was raided and “traces of explosives” were found in his bathtub.

Then the official line was that the explosives were home-made:
Police sources quoted in British newspapers said investigators now believed the explosive used was TATP, or triacetone triperoxide, a compound that can be made from easily purchased chemicals and is similar to the material used by attempted "shoe bomber" Richard Reid.

Then the home-made explosives got a surprising touch : perfume.
BOMBER Jermaine Lindsay bought innocent designer perfumes and aftershaves as a deadly mix for the London gang's home-made devices, police fear.
Just days before the 7/7 explosions killed at least 55 people, the 19-year-old Jamaican fanatic spent £900 at three shops on dozens of bottles of scent.
The names - Jean Paul Gaultier, Fahrenheit, Emporio Armani and Boss - are the epitome of "decadent" Western luxury.
(…)
"The effect would be more incendiary, like napalm, rather than highly explosive. It would create more more fire and therefore more burn injuries."

And today the whole story changed again: actually nobody so far has the slightest idea what kind of explosives were used in the blasts in London 13 days ago:
But Sir Ian said that at a briefing he attended, "It was made absolutely clear we do not know what this is." (…)
Professor Hans Michels, of Imperial College London, said analysis of the mixture of liquids and solids would take time because there might well have been chemical reactions during and since the manufacture of the explosive.
Any mistakes could lead to loss of life as well as vital evidence. "One wrong step and the whole building could blow up."
He said the analysis would be a "painstaking, tedious process. If they knew by the end of the week they would be doing a good job".

I don’t know.
I’m certainly not an expert. But I’ve never ever heard that the analysis of explosive material takes so much time and that so many different and contradictory results are told.

I love this Democratic Underground...very informative story and with links.
this bud's for you.:toast: have another..:toast:

DU is the best discussion board out there. Why would you post anywhere else? :D

I often post in AOL's politics from the right.I am pitifully outnumbered and often insulted,but I continue on spewing Facts I garner from this "Democratic Underground".From time to time I have successfully helped 1 goper find the truth.If I can open the eyes of the blind hey,makes me happy and they could help taking back our country.Its not the Dems who block us,its those damn gopers...So I thanked John Doe for linking me to those stories..i can now pass along those sites to unbelievers...that simple

hello everybody on du!

thanks john doe II for this. VERY interesting.
but i've no clue why all this turns are happening.
should be easier to analyse explosives, shouldn't it?

Especially if you claim to have compared them with traces at the home of one of the perps and found a match.

On edit: and oh, didn't they say they found a van at Luton FILLED with the same kind of explosives that were used for the bombing? So it's not just traces, but a sizeable quantity of the actual material used. Two weeks later, tbey still don't know what it is? Color me suprised.

They found the "bomb factory" and the van filled with explosives on July 12. It should have made their analysis much much eaiser.
And DemInDistress that's for you

thanks a lot for the warm welcome!
i'll check out if i find any example how long it normally takes to analyse explosives.
there are not many threads on london here. is there any other section specialized in london?
sorry, i'm new.
thanks!

"GE Ion Track, a leading provider of explosives and narcotics detection and identification equipment to law enforcement, military and security professionals, recently introduced StreetLab - a portable explosives and narcotics identification system that offers an entirely new solution to the problem of analysing unknown seized substances in the field.
While GE Ion Track's EntryScan3, Itemiser3 and VaporTracer2 are trace detection systems for analysing invisible particles and vapors, StreetLab is a bulk identification system for identifying visible powders, pills and liquids.
Utilising Raman spectroscopy - a technology already widely accepted in the forensic community - StreetLab identifies substances based on their molecular structure. Raman spectroscopy permits samples to be analysed non-destructively and can identify a wide range of substances from narcotics to solvents to liquid explosives. Unlike chemical tests, results are clear, repeatable and completed in a single operation.
Equipped with a near-infrared laser, StreetLab analyses frequency shifts in the light scattered off a sample to recognise the 'spectral fingerprint' of a substance, even if it is dissolved in water or other liquids. StreetLab can also analyse samples through transparent glass and plastic containers, thereby eliminating the need to remove packaging prior to analysis."

i'm not expert but this doesn't sound like an analysis would require several weeks.

explosives, IMO.

:toast:

is discussed in the September 11 section.

Welcome to DU!! :toast:

nt

Here's my theory on why so many contradictory explanations on the type of explosives used:

It WAS military explosives with timers as first reported. But that didn't fit the suicide bomber profile the gov't wanted to blame. In fact the explosives were planted and detonated by MI5 on behalf of the Anglo-American banking establishment which wants to use the threat of terrorism to convince the public to relinquish their civil liberties.

Just a gander...

Obfuscation is only necessary when there's something to hide.

LONDON - Police radically revised the timing of the deadly blasts that tore through the London Underground, saying Saturday that the bombs were detonated just seconds apart — not 26 minutes as first reported. The explosions were so intense that none of the 49 known dead has yet been identified.

or is that another false lead?

I have a feeling that false information is being fed to some media outlets -- just to confuse the citizens.

Thanks for keeping on top of this story . . .

for them to figure this stuff out?

The issue here, i think, is either:

1) The explosives for all devices weren't identical, because they were only able to obtain so much of a few different HX materials. So, the analyses are not confirmatory of one another.

2) The explosive were HX compounds, but were homemade. It's really not that hard to run a small reaction system to make nitrated organics. Most MS Chemists could do it, even if they've never taken a nitro-organic class. As a result, the purity is not terribly high, just enough to be fully detonatable. The residue of the compounds would then not be highly specific on NMR or Mass Spec and would require significantly more interpretation than expected.

Why would they buy expensive perfume? Aren't there less expensive forms of alcohol?

:rofl:

I have some ideas....
:toast:
:beer:
:party:

and it wouldn't raise as much suspicion as buying perfume for 900 £...

they knew this:
The bombs used in London's terrorist attacks held less than 10 pounds of explosives, police said Friday (...)
''Initially, the forensic investigation suggests that each device used had less than 10 pounds of high explosives,'' Hayman said. The weight of explosives was smaller than recent bombs detonated in the Middle East.

So, within 24 hours they know the amount of explosives that have been used and can even compare them to other bombs and yet after two weeks they have not the slightest clue what the bombs were made of (so in fact the explosives that were conveniently left behind in the van might have been made by something totally different and therefore not proving that the three driving in the car are in fact the culprits) ......
