We never hired anyone there as the skill level was above the average worker.
Don Tyson is the King of bringing bus loads of Mexican labor to NW AR. To staff his Chicken and Turkey Plants! Which ultimately affected the Construction industry with cheap underbid projects. Not all Mexicans wanted to stay Chicken Plant workers.
Anyway, Bill Clinton started Basic Pilot and Tyson was one of the first companies to use that. Tyson(or any company participating) checks their new hires against fedgovs list and if the new hire is on the list, they can't hire them. It catches a lot of them, but it wasn't foolproof so some illegals slipped thru the system. They all knew it wasn't perfect. Tyson knew it, Clinton and fedgov knew it.
But Clinton thought Tyson was gaming the system. That Tyson was targeting illegals in their recruitment programs, knowing that a percentage of these illegals they were targeting would slip thru the system.
So in 1998 Clinton went after Tyson on a criminal prosecution. Before this the govt only used civil prosecutions. And Clinton was going after corporate management. The Justice Dept ended up with over 200 indictments but when the case got into court the judge thru all but a few of them out.
The verdict came down in 2004 when Bush was prez and there were only two convictions with the jury foreman saying that if fedgov can't accurately say who is legal and who is illegal, how is Tyson supposed to know or say who is or isn't. They convicted a couple of local Tyson plant managers in MS and LA for knowingly hiring illegals.
That decision set the precedents for Bush and Obama. Criminal prosecutions are few and far between. Mostly civil prosecutions.
