I always thought this was the dumbest thing. An employer can't tell if a worker is legal, but I bet if the same guy was selling a used car he would be able to tell how many credit cards he had in his wallet and how much he owed on each one. An employer saying he does not know if a worker is legal or not is just so laughable.We can't fine the employers of illegals because they claim to not be experts in the immigration field. But now, the police are expected to be the experts? No, not experts, just arrest Mexicans. You'll be excused for the ones you get wrong by the laws of Arizona. This will never last.
