And they have no right to. You cannot prosecute a perceived threat before it has actually happened. Where on earth is that just? Because I could cause an accident, I am not permitted to act freely--by my own judgement? Not because I will cause an accident, or ever have caused an accident: just because I might?
People need to take responsibility for their judgement back before they forget how to judge. Judging by the receptivity to regulations like every one you named, I have to wonder if they haven't already.
