Are you saying that the illegal aliens themselves are a federal issue but once the federal government neglects their duty to confront the illegals, any action by the state regarding the illegals is a non-federal issue?
The state can't force a business to be an accomplice to a federal crime. It is a federal issue when that happens.
The municipality laws have to do with “day laborers”...not illegals. True, some day laborers may be illegals, then the feds should go after them.
But I’m in my mid 50’s and there have been areas in our town where day laborers congregate..and this has been going on for as long as I can remember. If a person needed somebody to help with a big job they’d go by and hire a few men for the day. They weren’t illegals...alcoholics, yes; bums, yes, but not illegals.
