In the early morning of March 12, 2004, a police officer searching through the wreckage of the Madrid trains bombed the day before (see 7:37-7:42 a.m., March 11, 2004) discovers a bag containing 22 pounds of explosives surrounded by nails and screws. Two wires run from a cell phone to a detonator. Police use the memory chip inside the phone to find who the owner of the phone has called recently. They quickly discover a network of Islamist militants, many of them already under surveillance. They hone in on Jamal Zougam, who owns a cell phone shop that is connected to the phone, and who had been under investigation for militant links since 2000 (see 2000-Early March 2004). He will be arrested a day later. But the ruling party has already blamed the bombings on ETA, a Basque separate group (see Evening, March 11, 2004). Interior Minister Angel Acebes had blamed ETA within hours of the attacks (see 10:50 a.m.-Afternoon, March 11, 2004), and again he publicly claims that ETA is the prime suspect, even though police are now sure that Islamist militants were behind the bombings instead. He even calls those who suggest otherwise “pathetic” and says their alternative theories are “poisonous”. But news that ETA is not to blame is already leaking to the media. That evening about 11 million Spaniards protest around the country—about one fourth of Spain’s population. They are protesting the violence of the bombings, but also, increasingly, growing evidence of a cover-up that attempts to falsely blame ETA. The New Yorker will later comment, “It was clear that the [national election on March 14] would swing on the question of whether Islamists or ETA terrorists were responsible for the bombings.” [Guardian, 3/15/2004; New Yorker, 7/26/2004]
