I believe it says that the constitution and all laws pursuant to it are the supreme law of the land. Unconstitutional laws are not the supreme law of the land.
True, but you ask can a State law nullify the patriot act. The constitution can, but not a state law.
That is correct. Its the constitution that does that not state laws.
The patriot runs a fine line with the 4th amendment, but it you look at many 4th amendment cases they go onto intrusiveness. For example, thermal imagers have been held unconstitution without a warrant, but dog searches have not. They are about intrusiveness.
