The video I saw on the news was enough evidence for me. Are you saying that was faked? And in any case, as far as I'm concerned any level of violence is unacceptable. Madrid made itself look like a tin-pot dictatorship, which is particularly unfortunate given its history. It would have been far better to let the referendum happen and say 'and'? Reacting with violence demonstrated fear, not strength, and if anything seemed to strengthen the case for independence.
