Is time to protest in Spain? (II)

This morning, Barcelona's police acted in a stupid way against the "Indignados" in Plaza Cataluña.
The Police turn a pacific protest of people armed with flowers into a violent riot without any justification.
This afternoon the people had congregated again in the same square in the center of the city.
I don't know if the Police is going to act again in the same way, or they are going to leave them free.
