This would seem to be a federal crime.
Law enforcement officers should come to the aid of anyone asking for help, and federal officers are no exception.
Certainly ordering local officers not to come to the aid of federal officers in trouble, would be problematic.
Sounds like a civil rights violation.
I agree...If not a crime it’s certainly pushing the limits to the max.
Wheeler can say all he wants about only sending police in a life threatening situation, the protesters (including antifa) that were camped outside the ICE building were a life threat for over a month.
They have no duty to respond, legally.
