Well, if Liberty is the first, then we better scrap all forms of ID, port-of-entry security, etc., 'cause they're all infringing on our precious freedoms!!
But then, as someone else said, if you're not safe, you're not really free, are you?
Freedom trumps Safety because there is no point in being secure if you are a slave. And no I am not an Anarchist so I do not suggest we ban all ID because even the founders knew that government must govern to a certain extent. However dogs are considered personal property and when the gov interferer's in what people can or CANNOT do with their own money, well that is where we differ.
