I totally agree. Many liberals act like people can now be pulled over for being Hispanic or for listening to Tejano music. Cops in Arizona will not seek papers unless they have other reasons to pull the person over or to be at their residence. If an American gets pulled over for not using our blinker, we have to produce ID. The same should be done for everyone, if a person cannot produce ID, can’t speak English and can’t say where they live, that seems like enough reason to check their citizenship.
The final arbiter should be the Supreme Court, not the Obama Administration or US Congress.
The people of Arizona should have the right to enact and enforce their own laws and the federal government should butt out, especially since the federal government won't enforce existing laws to protect our nation against invasion and invasion is exactly what's happening.
already dealt with:

Cops know it well.
