The commuter trains that pass through eastern Madrid on their way to Atocha station are one of the primary routes for the daily influx of thousands of students and workers into the city, writes Alberto Ruiz-Gallardon, mayor of Madrid. In this article, the author cites Madrid as a historic bastion of freedom that now defends freedom for all Spaniards with the same determination to not give in to the oppressor that has always given us courage. We must denounce not only those who were materially responsible for this collective assassination, which has already been recognised as a crime against humanity, but also those who are intellectually complicit, who with their silence or indifference contribute equally to make such acts possible. The best way to not give in to the ferocious attack inflicted on us yesterday as members of a free society consists in not losing sight of these people who yesterday, as on any day, made their way to Madrid to give the best of themselves, not to be remembered as victims but as what they were: passengers on trains that carried the life of the city.
