Many protesters observed the use of multiple drones at the West Contra Costa County Detention Center on June 30, 2018, during a protest against ICE and its practice of family separation. Journalist Darwin BondGraham wrote about this in an East Bay Express article on July 3, 2018. Documents released in response to a public records request indicated that the drone was also flown over the June 26, 2018, protest at the same facility.
The Contra Costa County Sheriff’s drone (or unmanned aerial vehicle/system) program was started in 2016. The agency purchased its first drone on September 7, 2016, a DJI Phantom 4, from Fry’s Electronics on Willow Pass Road for $1,685.14. The drone was returned and exchanged for the same model on September 13, 2016.
