They cannot deport people. They can transfer folks to the Feds, and can hold them for the feds, but they can’t send them home.
Depending on local enforcement isn’t going to help, not in the short or the long run. Essentially it means that the war is lost. Now you’re depending on cities to enforce what the country will not.
I hope you can see why this strategy is a losing strategy. the Feds have to uphold the law.
Why can’t States enact laws to force their Congressional representatives to introduce and vote for impeachment of federal officials that do not enforce laws they have sworn to uphold?

IIRC, Florida threatened to send the Haitians washing ashore in the 1990s up to Washington DC if they weren’t assisted in dealing with them. The governor was furious that he wasn’t supposed to take action while they turned southern Florida into another Haiti.
So, what authority are they operating under?
Most federal law is administered, in part, by state and local authorities and always has been.
Give you an idea how this goes down. We had a neighbor here who was a car salesman and "dealer". He discovered that he could sell a lot more cars if he focused on dope dealers and simply quit reporting sales over $10,000 to the federales. Over time he worked out quite a scheme.
One evening our very long cul-de sac was jammed with cop cars ~ starting with the FBI, Treasury, Postal Inspectors, Military Police, Park Police, Virginia State Police, Maryland State Police, West Virginia State Police, and representatives of every municipal authority and sheriff's department for 100 miles around.
He'd kept records. The cops were there to get them, or help identify them, and they dismantled the interior of the house removing the records he'd hidden behind the walls for years and years.
It was a multi-jurisdictional bust.
I didn't see any LA RAZA or ACLU demonstrators or lawyers present.
