And, actually, the entire question is bogus and just one more something concocted to create confusion around the illegal alien issue. We all run the risk of being questioned, or even becoming a suspect in some crime or other disallowed act we know nothing about. It's just part of being alive and functioning in society.
I was once arrested and spent the better part of a day in jail for non payment of child support I didn’t owe. (I don’t have kids) It was an inconvenience but I sure didn’t see it as a civil rights violation. It was a courthouse screw up and easily dealt with.
Another time I had a cop pull a gun on me. The cop even had me on the ground in handcuffs before I could prove it was a case of mistaken identity. The cop got my ID and showed me that I was a dead ringer for a murder suspect. My friends and I all got a laugh out of that one. No harm, no foul.
