"if you haven’t done anything wrong you have nothing to fear”
I've just applied some basic logic circuits to this one (with all due precautions on overload/paradox etc.) and observed the following..
1. The only people who are afraid of this legislation are people who understand it technically and how it will affect the relationship between the people and government
2. The only people who understand this legislation in this sense are intelligent and have a moral conscience/sense of preservation for the whole of society and not just themselves
Therefore, for the original statement to be true, it can be considered 'wrong' to be both intelligent and have a moral conscience.
Now you know what the people who utter that phrase really believe.
