The figures I mention here come from a joint report done by Provea y Espacio Público, which is an organization that works on freedom of expression and includes demonstrations as well. They are consistent figures, because they have contact with the trade unions and the peasants' organizations, and they do follow some cases in the legal system, such as the one I mentioned, that of Rubén González among others. So I think there are enough grounds on which to think this information is reliable.
With regard to safety and security, I personally don't have any problems so far, but there are others who have had those problems. That doesn't make me any happier, but I don't want to be a target anyway.
