I lived in Spain for 2 1/2 years - 1/2 year in Madrid, and I felt so horrible for what happened.
My heart goes out to the Spanish people.
I hope there is no backlash against innocent Morrocans and Arabs like there was here in the USA. I know that there is a lot of discrimination against Arabs and Africans in Spain as it is.
I hope Spain can get back on track quickly and that nothing like this ever happens again.
