A few years ago there was a huge set of raids at Tyson facilities - 900+ undocumented immigrants working there.

Awkwardly, it was made known to the media that Tyson knew all about it, to the point where they had provided those workers written instructions and tips on how to stay under the radar with respect to taxes, financials, immigration, etc.

When a journalist asked about this at the press conference where DHS was crowing over the success of the raid? "That's not something that is being investigated as part of this operation." Well, what about separately? "We are not investigating the company."

A lot of the theory was that like some other food production firms (Hormel dealing with people getting sick from y'know, inhaling aerosolized pig brain), that it was very much a "won't someone rid us of these meddlesome immigrants" (the ones advocating about child labor, wage theft, OSHA violations). Come round these ones up, you get a press conference and we solve a labor issue.
