Responding to the decision, ACLU of Florida Executive Director Howard Simon stated:

"We are disappointed that Mayor Gimenez has instructed county officials in Miami-Dade to comply with federal detention requests. At the very least, a warrant from a court, not merely a request from a federal official, is required to detain somebody in jail. We will resist every attempt by our government to punish immigrants, regardless of their status.

“Today's decision by Mayor Gimenez flies in the face of Miami's long history as a city of immigrants. It also flies in the face of the advice of professional law enforcement that policies like the one Gimenez embraced today serve only to drive a wedge of distrust between law enforcement and our immigrant community."
