Actually it is the Feds business. They should be there busting illegals and shipping them back home.
These labor sites are mostly ilegals hanging around looking for jobs. Send the illegals home and the problem is solved.
It also legitimately falls under interstate commerce.
Illegals are their business, and granted, day laborers are mostly illegals, but it's still none of the feds bizness if a local gubmint hassles a business about a day labor shelter.
Why doesn’t Home Depot have them removed for trespassing? Parking lots for businesses are usually private property. And I’d say loitering alone should get them removed. Laws for some, but not for others?
