@yura I could go on and on, but the thing is that you don't have to dig that deep to apply some degree of accountability to pretty much everyone. There's too much laundry to do, too much to sort out even for courts and tribunals. And the victims would demand justice and accountability and the guarantee of NEVER AGAIN right this f*cking instant.
So, the society came up with nothing better than a presumption of guilt (until proven otherwise).
