I wonder if this letter is truly from Guardia Civil or is it from someone else impersonating it. The content reads amateurish, such as the claim "Tsunami Democratic's main goal is coordinating these riots and terrorist actions by using any possible mean" without refearing to any specific actions or events. The assertion that Tsunami Democratic has been declared a terrorist organisation by National High Court is simply not true, and no official communicate would reference the media as a source. I wonder if this is the reason why the content is still available on Github (at least from Norway)
