Would stop drivers for traffic violation,
which is PC
then detain passengers for being in country illegally which is not a criminal violation.
i am pretty sure that it's illegal under arizona law
if you're detained for an illegal act, and then investigated for another illegal act, it seems like it doesn't violate your actual constitutional rights. now if you want to jump on the twisting and expansion of federal powers (that funny enough isn't in the constitution), then you can argue it
but since your initial comment was re; tea partiers, and they reject this expansion of the federal government, your claims of hypocrisy or ideological inconsistency don't really work
