Yes it does. When I contracted for my driveway I didn't inspect the contractor's crew upfront and neither does anyone else. When I got a look at them, I turned him in. I don't know if anything happened with it or not.
The way I understand it, he found out about the illegals when it hit the press. I don't know that he even saw the crews. If you can prove that he did, go ahead and prove it.
EVERYONE does not hire illegals. And lots of those who do, know.
