Edited sentence: There has never been an actual case of human rights violations directly caused because of the tactics learned by former students of the SOA or WHINSEC.There is no "cause and effect" credited to these actions.This system prevents any student from having a seat at the school if there are human rights abuse accusations against them or against any unit they were a member of.To say that the three weeks that a given student spends learning will shape his decisions into committing atrocities rather than the years of turmoil in their country is laughable.WHINSEC in recent years has put into place a vetting system aimed as preventing human rights abusers from gaining a seat at the school
