The Oro Valley Police Department has become the second local law enforcement agency in the Southern Arizona region to begin regularly using drones.
The idea came from the 2017 Oro Valley Music Festival in September, when the Sahuarita Police Department, the first in Arizona to purchase drones in late 2016, agreed to provide its drones for the event. It allowed the Oro Valley officers to better adjust for crowd management, move officers around and watch for problems.
โIn doing this we realized that we needed to tighten up a few things,โ said Lt. John Teachout, who oversees the Oro Valley police drone program. โWe moved folks around, we moved some of our resources around and we could also make sure people werenโt entering the venue from areas that werenโt authorized.โ
Oro Valley Police Department Lt. John Teachout mounts the rotors on the new DJI Matrice 200 commercial-grade quadcopter at the OVPD station on April 17, 2018 in Tucson, AZ. This unit, which requires some assembly prior to flight, is used to map crimes scenes and do aerial searches. It is equipped with a 20 megapixel camera with changeable lenses.
Days after the festival, a gunman opened fire on 20,000 people at the Route 91 Harvest festival in Las Vegas, killing 58 including Christiana Duarte, a recent University of Arizona graduate.
The department took notice and purchased three drones from Chinese drone manufacturer DJI. Two of the drones cost $1,000 each and the third, a Matrice 200 Series, cost $5,000 and can be equipped with different camera systems and be flown in bad weather.
The department first used a new drone to search for an elderly woman with dementia who strayed from home in January. She was later found by a patrol officer. A drone also took aerial photographs of a crime scene.
Drones also can map the scenes of vehicle collisions to help investigators determine what happened, allowing roads to be reopened more quickly, Teachout said.
While the unmanned aircraft are not a replacement for helicopters or other large aircraft needed for major incidents, smaller events can be handled in a more cost-effective and safer manner with a drone.
DJI says it makes some of its drones specifically for police.
โSmall UAVs that can fit in any police vehicle give law enforcement teams broad situational awareness, allowing them to formulate an appropriate response in even complex and testing environments,โ the companyโs website says.
The department has seven officers who can fly the drones and who are licensed by the Federal Aviation Administration. The department conducts ongoing training to ensure that officers retain their flying skills.
Community outreach is an important part in using the drones, Teachout said, and the plan is not to operate them surreptitiously.
โWeโre well aware of the constitutional limitations as it relates to the Fourth Amendment, and we tell the public what these things are intended to do, itโs not to go peering into peopleโs back yards out of curiosity, itโs purpose-driven,โ he said.
Teachout said the department follows guidelines from the International Association of Chiefs of Police on how the drones should be used during police incidents.

One of the associationโs guidelines directly addresses privacy.
ยกIt says if the department believes the aircraft will collect evidence of criminal wrongdoing but also intrude upon a personโs reasonable expectation of privacy, the agency should secure a search warrant first.
โWe think that these tools, while new, are going to be a more efficient way for your police department to provide better and more expedient service to our community in a cost-effective manner,โ he said.
