No one is asking them to enforce it. This article states that will purposely not even notify ICE, collect information, or share information.

No one is asking DPD to go round up illegal immigrants. That will obviously never happen. But to turn a blind eye and let wanted criminals go is wrong.

Would you feel the same way if a man wanted on federal kidnapping charges were locked up in Denver? The DPD has no obligation to let anyone know because it's "not their job?"
