There is if you are a county sheriff who doesn't have that authority.

And there is something very wrong with US immigration policies.

I agree with both points. Police officers do not and should not have the authority to enforce the law, and anything that stops people from going to the United Sates is wrong. So clearly companies are violating our privacy when hired by law enforcement to examine public records in order to catch them and send them back to their own country. I admire your courage in standing up for all Americans, especially the 7.2 Billion Americans (7.5 Billion - 300 million) who happen to just not have citizenship yet.

I believe that depends on whether there's anything wrong with your country's immigration policies.
