It is to agree with the fallacy that God only grants inalienable rights to native-born Americans, while the rest of the world are subjects, serfs and slaves, by birth.
God didn't say we couldn't search ZM's computer before the attacks. God gave us the unalienable rights to life (Thou shalt not Kill), liberty and property (Thou shalt not Steal), and we should do our best to secure them.
The subject is the Bill of Rights. The 4th Amendment right to not be searched on a whim may not be a divinely endowed right. I don't think it is. It doesn't kill him or steal from him, to violate it. Searching ZM's computer in violation of his fictitious 4th Amendment rights would have helped secure many other lives and lots of property in downtown Manhattan. Bob Barr made no exceptions for the 4th Amendment. He was therefore wrong.
