Sheriff Joe Arpaio's deputies and volunteer posse are carrying out a crime suppression operation in southwest Phoenix on Friday. It is the first of its kind in two years, and it comes just weeks after a federal judge ordered major changes at the Maricopa County Sheriff's Office, in light of his finding that the agency discriminated against Latinos.

The sheriff's office said the two-day operation is targeting gang members in response to the August shooting of a detention officer and will involve arrests for drugs, illegal guns and outstanding warrants. But Judge Murray Snow's recent order against MCSO requires the agency when doing these kinds of operations to share written plans in advance with a court-appointed monitor.

Except, a monitor has not been appointed yet.

On Thursday, the sheriff's lawyers filed that notice directly with Judge Snow under seal.

The plaintiffs who brought the racial profiling lawsuit against the sheriff submitted their own statement to the judge saying the agency appears to be circumventing the judge's order for oversight.
