Nearly a year has passed since the U.S. Justice Department launched a civil rights investigation of Phoenix and its police department.

The city so far has spent a little more than $1.5 million for the inquiry.

Phoenix remains under federal review for allegations of excessive force, discriminatory policing, retaliation against protesters and mistreatment of people living on the streets.

To date, most of the city’s roughly $1.5 million price tag is to pay the salaries of nine employees assigned to work on the review.

Another expense comes from the need to gather and prepare records for the Feds. The city is paying for software, staff training and licensing.

Phoenix has also spent money on advice from the law firm Steptoe & Johnson and a consultant.
