For the prosecution case against the July 21st 'Dummy Bombers' not to be laughed out of court and viewed with deepening mistrust by sections of British society they'll have to overcome 2 obstacles.

1. Logic - Theres no such thing as half suicide bombers
Nigel Sweeney QC's notion that the quartet, armed with comical chemicals intended to murder and not cause public fear, transport disruption and nuisance to the ongoing 7:7 investigation (as an Anti-Terrorist detective confirmed they had) goes against the laws of logic and flies in the face of the evidence.

2. Science - Defying the its laws
The amounts of home-made TATP (Triacetone Triperoxide) they carried only dispersed gas upon detonation, enough to damage say...a rucksack as CCTV footage broadcast shows they found.

You don't have to be an eminent scientist to know that TATP does not release a burst of energy/fire as a typical explosives such as the C4 - used in the Madrid bombings.

TATP rapidly releases gas similar to that found in car airbags.
Yet the British media christened the self-raising japati flour based concoction the 'The Mother Of Satan!'

While MI6 gives the real masterminds frequent flyer freebies and funding, 'sources' tell the public that barely literate dummies such as these and the Richard Reids of this world will bring their way of life to an end if we don't hastily sacrifice our freedoms.
Hardly!
