It's a shame Velasco did not do anything about these failures in the market-driven model when he was Minister. In Chile the Minister of Finance is very powerful. In his explanation, he should have considered a dark question: how was it possible that tens of metro stations (70 according to some) were burnt down within a few hours, all apparently with the same method. I am averse to conspiracy theories, but this is very worrying: there seem to be elements in the security apparatus who are beyond the control of their commanders or of the president and who have some nasty intentions.
