Sounds like an interesting book.
Another thought occurred to me -- why should we have to "guess" at "why" our leaders would choose to do this?
If it is something that should have popular support (and, as a representative government, i believe it should), then it "should" be explained to the public as to WHY this law would be preferable to the alternative, explicit in what the alternative is (with examples of how that is both reasonable and probable alternative outcome without the law), and clear in how it would be implemented to protect our rights while simultaneously allowing for this exception/exemption.
