Hal,

A) Langley doesn't house prisoners, so how would "regulations that interfere with the ability of police or sheriffs to communicate with federal immigration authorities about the status of prisoners in their custody" apply to us?

B) The threats coming from Trump and his justice dept. are not supported by what's actually happening in the courts, which will ultimately rule on the constitutionality of these actions. Until then, I see  the threats on federal funding as nothing more than bullying and intimidation tactics by an authoritarian government. We all need to resist this kind of stuff, not comply in advance.   https://48hills.org/2017/04/14/trumps-lawyer-backs-down-on-massive-federal-cuts-for-sanctuary-cities/
