For what it's worth. My Mother is of the opinion that five alleged bombers are mercenaries, and were paid to do the attacks. She questions that surely if they were committed zealots they would have followed the example of the Madrid Bombers and blown themselves up or had a shoot-out with the authorities. Of course they may have tried to blow themselves up and this second set of devices failed like the first. In defence she is 86, though she lived through the blitz in London and escaped a strqaffing by the luftwaffe and a V2 which exploded in a neigbours garden.
