We live in a strange world where it is “dangerous” to force cities to comply with the law.
Has anybody anywhere spelled out the details of what is going on, or what it would mean.
As best I read the accounts and the debates going on about it, there is no actual current Federal law binding on these “sanctuaries” — only a moral obligation. The 10th Amendment is to thank for this. It probably was never constitutionally envisioned that state and city localities would ever WANT to be invaded — that they would fail to do what is right out of their own self interest. The welfare explosion has made what would have otherwise been unthinkable, lucrative.
Tying Federal welfare participation to a good faith effort to weed out the “undocumenteds” would only be sensible. You want to be don’t ask don’t tell — fine, but you will be don’t receive as well.
