Ars Technica reported yesterday on the Alameda County Sheriff’s Office (ACSO) acquisition of two drones. Of course, use of drones still needs approval from the FAA. According to the ACSO, “The reason for specifically acquiring this is search and rescue.” However, according to the ACSO General Order supporting the drone use, search and rescue is the 4th out of 10 uses. These includes two that are very broad — “post-incident crime scene preservation and documentation” and pretty much anything related to a felony.
Drones can be a good thing. In fact, for the stated goal, search and rescue, drones can be great. In comparison to other aerial surveillance options (e.g., helicopters or planes) they’re cheaper and easier to implement. ACSO says they’re spending $97,000 on this, which is a very little compared to a helicopter. And training is certainly a lot easier too.
So what should government agencies do when they want to use drones? The Electronic Frontier Foundation lists three requirements for drone legislation. While two of these deal with private and commercial use of drones, the third emphasizes the need for law enforcement to get a search warrant when using drones for investigative purposes. The Alameda County Sheriff’s Office policy, as currently posted, does not require a warrant for any use of drones. Similarly, the ACLU recommends that the following be included when government organizations implement a drone program.
- USAGE LIMITS: Drones should be deployed by law enforcement only with a warrant, in an emergency, or when there are specific and articulable grounds to believe that the drone will collect evidence relating to a specific criminal act.
- DATA RETENTION: Images should be retained only when there is reasonable suspicion that they contain evidence of a crime or are relevant to an ongoing investigation or trial.
- POLICY: Usage policy on domestic drones should be decided by the public’s representatives, not by police departments, and the policies should be clear, written, and open to the public.
- ABUSE PREVENTION & ACCOUNTABILITY: Use of domestic drones should be subject to open audits and proper oversight to prevent misuse.
- WEAPONS: Domestic drones should not be equipped with lethal or non-lethal weapons.
Note that one of these recommendations is that the public actively participates in the decision to set up a drone program. However, in Alameda County Sheriff’s Office situation, the Sheriff seems to have excluded critics from the process — EFF and the ACLU of Northern California only found out about the press conference from a story in the newspaper. And I’d go even further here. When a government agency sets up any program like this, including drones, surveillance cameras, automatic license plate readers, and so on, the public should be involved, there should be regular (e.g., annual) reviews of such programs, and independent evaluations conducted to determine if these programs are meeting the goals set for them. This can help eliminate wasteful programs and reduce “mission creep.”
I also want to mention the “public” survey that Sheriff’s office has touted as support for their purchase (given that my day job is actually conducting surveys). According to the reporting, they did get over three hundred responses. But this survey clearly suffers from selection bias — the people who responded to the survey aren’t representative of Alameda County residents, but people who attended a “Cop Shop Barbecue” (and paid $12 to do so).
While I wouldn’t necessarily be surprised if a significant number of people are okay with unfettered use of drones, the one poll I’m familiar with actually suggest the opposite. A Monmouth University poll from 2013 (PDF) showed that three-quarters of respondents wanted law enforcement to have to get a search warrant from a judge before using drones versus only 14% think that law enforcement agencies should be able to decide on their own when to use them.
