The vast majority of entries this week are about the 2004 Madrid train bombings and al-Qaeda in Spain. A suspect Spanish policeman sold a house to Moutaz Almallah, one+of+the+bombers, in 1995, some of the bombers could have been arrested in a general sweep of al-Qaeda-linked militants in Spain after+9/11, but were not, although one of the masterminds was photographed with top+al-Qaeda+operative+Barakat+Yarkas. However, surveillance of the bombers continued and an informant spied+on+their+secret+meetings. The police learned one of the masterminds was preparing for "violent+action", and another mastermind was surrounded+by+informants.
One informer monitored the bombers closely, and realized another of the alleged bombers also worked+for+the+police. The wife of one of the bombers gave police stunning+details about his activities in 2003 and they started monitoring a house used+by+he+bombers based on a tip-off from her. She warned police the bombers were planning a suicide+attack, and continued+reporting on the group. Police received a big+tip that could have prevented the bombings, monitored the apartment of one+of+the+masterminds, and turned+down+the+chance+to+videotape+the+bombers'+meetings.
