Well, there is that whole Constitutionally protected right thing. This law would effectively usurp that. It would allow the government to take away that right based on some nameless / faceless flunky's analysis and dropping your name onto a list. A list that by the way you can't see. A list that you don't know how to get on (or more importantly stay off of). A list that the procedure for getting off of if placed on there in error is both ill-defined but no-doubt time consuming and expensive.
Gee, and they wonder why we oppose this law? Secret lists, stripping rights away... That is the stuff of the Stasi and KGB, not America.
