Madrid Bombings - inside job?

During the trial, explosives experts explained that they had searched all the objects left in the train cars four times and confirmed that it was impossible that the found bomb had been among them [8]. Its origin is even more doubtful because the abandoned objects, among which the bomb was purportedly found, were moved 3 times throughout the day of March 11, not always under the best surveillance [9], and ended up at the Vallecas police station, contrary to what the judge had ordered. If one adds to this the conflicting testimony about when it was discovered [10], the fact that the bomb was not mentioned in the inventories of abandoned objects [11], and the fact that there are no photos of the bomb before the time that it was dismantled, the inconsistency of such evidence becomes clear. Notwithstanding all this, the court used it as a key element in rendering its verdict.
