A temporary injunction has halted the most useful parts of Arizona's law. The injunction, courtesy Legal Insurrection, notes that:
Thus, an increase in the number of requests for determinations of immigration status, such as is likely to result from the mandatory requirement that Arizona law enforcement officials and agencies check the immigration status of any person who is arrested, will divert resources from the federal government’s other responsibilities and priorities.
Free healthcare, prescription drugs for all, and an increasingly bureaucratized education system—a mere handful of the priorities that she must be thinking of—appear not once within the literal text of the Constitution.
Even though the Constitution lays them out as the Federal government's explicit responsibilities.
So goes the upside down world we're forced to inhabit.
