Nearly three weeks after an unarmed Black man was killed by a White Phoenix police officer, dozens of protesters continue to snake through the streets of Phoenix, demanding justice for a shooting they say amounts to police brutality.

Each demonstration also draws secondary crowd, a silent police presence that shadows but rarely engages the protesters.

The protests have remained non-violent, with no arrests or property damage. But they have not come without a price: additional overtime for officers.

As of last week, overtime costs associated with policing protests related to the shooting of Rumain Brisbon have exceeded$116,000, according to Phoenix police. The figure does not include costs that may have been incurred Saturday afternoon, when about 75 demonstrators briefly marched down the light-rail tracks in downtown Phoenix and staged a "die-in" near Maricopa County Superior Court.

The tally still exceeds the price of other big-ticket overtime events from this year, including surveillance during a visit by Vice President Joe Biden, the P.F. Chang's Rock 'n' Roll Arizona Marathon and the funeral in March for Phoenix police Officer John Hobbs, who died in the line of duty.
