There has hardly been due legal process. The Free Aceh Movement is a political reality in Aceh. People are not sure of its strength but clashes have clearly led to deaths among police and military. But what is important here is that because there has been no upholding of the law, GAM has received public sympathy, more so among people whose parents or relatives have become victims of the military operations. People have turned to GAM for a sense of security.
People can no longer wait.
But if public reactions are not as the government expected that's a different thing. Political settlement to calls for a referendum should also be addressed. It would be impossible to restore trust in the government if the government ignores the people. A simple small step to restore trust would be to have people informed if military or police members are sanctioned by their superiors for having violated rules. The police and military may say they are avoiding anything untoward by not exposing those sanctions, but mistrust will continue if the public does not know of such unexposed sanctions.
