Demonstrators march towards Puerta del Sol plaza in central Madrid, Saturday May 12, 2012. Demonstrators arrived in Sol from four different directions as protesters returned to Sol to mark the anniversary of the protest movement that inspired groups in other countries. The protests began May 15 last year and drew hundreds and thousands of people calling themselves the indignant movement. The demonstrations spread across Spain and Europe as anti-austerity sentiment grew. Banner reads '"Violence is earning 600 euros a month". (AP Photo/Paul White)
