By the way, You did not post this yesterday (at least not on this thread).
Thats a federal law that enlists state law enforcement in apprehending those in violation of federal law. Try again HEEROO. The regulation in matters of immigration and naturalization is strictly a power of the federal government.
In making Immigration laws, yes, but in enforcing immigration laws, no.
Your argument was the enforcement of immigration laws. There is nothing in the US Constitution that prohibits the States from enforcing immigration laws. The states could close down their borders with Mexico and Canada if they wanted to, the protection of the state border is in the hands of the states.
They absolutely could not. You work for the INS and are really this stupid?
