They should also be arresting the enablers: The politicians and bureaucrats who create the “Sanctuary cities”.
4 months ago the head of the CAL senate Kevin De (added for ethic emphasis) Leon admitted half his family is illegal and he helps them. No investigation, no arrests. When a mayor and city council implement a policy to not call ice when they release an illegal from jail and they rape, rib, or murder someone those politicians are culpable in murder. Nothing happens.
