The ones who contributed to this crime did so because they are opportunists who aimed at taking the positions of authority. They did it so blindly and foolishly, as if the military regime would allow them to rule. After they collaborated with the military regime and made deals with it.
All what the military regime needed to do was to let the public know what those who were colluding, were hiding in order to appease the masses, to de-popularize them as well.
So, in the end, nobody wins and the military regime won, as usual.
Thanks for the selfish and the opportunists!
