My difference with you may be who is the 'they' in the above statement. It is more like 'we the people' in the above statement. It is our democratically elected representatives that are discussing the law per the OP. Yes, there is some trade-off between privacy and making society more safe. It is our representatives that make this judgement call. Who hires these people and pays these people? It is we the people. It sounds like you are thinking there is some hidden conspiracy against our rights. Who is leading this conspiracy and How? and Why?
So gosh-darn democratic it makes ya wonder why lobbyists waste their time, don't it...
