Huh? Allende was no saint either, he certainly used violence directly. One of the biggest complaints about Pinochet was that he did everything that Allende was accused of (including torture) but worse, of course Pinochet was in power for a longer period of time.
What accusations are you talking about? Allende did a lot of things some may consider questionable (land redistribution, statization) but torture is usually not among them.
There was some preparation for guerilla operations, from both sides, in case a coup happened (as it did) and some armed resistance to the expropriations (which were legal according to the then valid laws).
"g) It has made frequent politically motivated and illegal arrests, in addition to those already mentioned of journalists, and it has tolerated the whipping and torture of the victims;"
So, you are bringing up a document used to justify the coup as a credible source of accusations that were never proven in the years following its original publication, despite the interest of a government that used violence routinely to prove them and justify its own brutality as a lesser of two evils.
Excuse me if I find it difficult to believe in it. I don't think you should take it as a representation of the truth either.
Sorry, but your criticism is equally valid for basically any sort of legal propaganda, for example the Declaration of Independence. Moreover, I don't know how hard you've tried to actually compile evidence that "accusations... were never proven in the years following its original publication" - since you clearly weren't aware of those accusations, say, 24 hours ago.
Also your history is wrong; the document was used to justify 'impeachment' (because such a concept did not exist in the chilean constitution); the coup itself came afterwards, when Pinochet wrested his leadership of the military into overall civilian leadership, and I would not be so sure that the authors of the document intended the course of action that happened to be an indirect consequence of their petition.
The document, btw, passed the chilean legislature 81-47, which while not the two thirds required to remove the president, is still quite a supermajority.
Anyways, I think it should be the default assumption that governments torture people. There are scant few that haven't.
You are being very naïve if you think Chilean legislature had no idea of the impending coup. As for the lack of evidence, I tried to find some and came back empty handed. If there were anything even distantly resembling the systematic use of violence Pinochet employed made by the Allende regime, I'm quite sure it would be amply documented by now, if, by no independent historians, by the Chilean military. Since I can't prove it didn't happen, do you have anything more solid than this to demonstrate it did?
