What illegals?
You yourself said that you have no proof that there are even any there.
I would have more respect for your position if you weren't assuming that there are illegals there.
We constantly make the argument that Americans would do the jobs that illegal immigrants are here doing, well, maybe that's who is there.
Why don't you take the time to find out who stands on that corner?
If they are illegal immigrants, then do what you have to do.
