SLAVE OR FREEMAN LEGAL OR ILLEGAL. During slavery, blacks were profiled. When they traveled away from the plantation, they had to have papers with them showing what plantation they were from. They had no problem carrying those papers and showing them because they could be taken away as a run away slave and taken from what families they had. Free slaves had to carry paper showing they were free or they would be taken back into slavery. And they was the only way you could tell a free slave from one who was not. Who why do Hispanics who are a large population of illegals in Arizona have a problem carrying papers identifying if they are legal or illegal. That is because there is a large population who are illegal and 90% or Hispanics would produce an illegal. DUH? Hispanic carrying paper identifying who they are is a protections for them as it was for slaves and freemen. Candidates running for president have to produce a birth certificate showing that they are a natural born citizen. What the hell is so special about Mexicans that they cannot show they are in this country legally. If you work at Walmart, a member of congress you have to show and ID. Everyone in the country have to carry an ID except Mexicans?
