Video: Study says local immigration enforcement is wasting money

Section 287(g) of Federal Immigration Law allowed Maricopa County Sheriff's deputies to train with federal ICE agents in detecting and arresting illegal immigrants.

"These 287(g) officers aren't making us any safer, claims Bob McWhirter, "They're spending most of their time chasing after gardeners and dishwashers - people without criminal records."

A non-profit research group called Justice Strategies says the 287(g) program has "corrupted" criminal justice and is a misuse of funds. The group also calls for a federal investigation.
