Despite these benefits, the ACLU wants to restrict the use of DFR programs.
The ACLU concedes that law enforcement use of drones during emergencies is  constitutional. But the problem lies in definition of emergency. What the ACLU  considers proper use of drones by police is implied in its criticism of the  nation’s first DFR program in Chula Vista, CA.
The report says the Chula Vista Police Department has launched more than  14,000 DFR flights since the beginning of its program. Some of those flights  were for things that the ACLU considers emergencies such as fires, vehicle  accidents, and “gun violence” (crimes committed with firearms). Others were for  things the ACLU considers less serious, and that merits a deeper dive.
Some very serious calls for service—family and domestic disputes, wellness  checks, and mental health incidents—should not be considered emergent enough  for a drone overflight in advance of your arrival, according to the ACLU. These  are all very dangerous types of calls. It is not unusual for officers arriving  at domestics to come under attack—and sometimes under fire—from the partner or  family member that caused the problem. A welfare check could be the pretext for  an ambush. A mental health call can rapidly escalate into a suicide-by-cop  incident. There’s not a cop in America who wouldn’t love to have more  information on these situations before rolling up on them. And to deny you that  information on the grounds of the possibility of abuse of the technology is  wrong.
The report also cites nuisance calls as a reason Chula Vista PD has sent in  the drones. And it implies that the agency shouldn’t be allowed to do so. There  are many reasons why this is wrongheaded thinking. But the primary one is that  even if it is a nuisance call, once you receive information from the  dispatcher, you have to go. Cops aren’t allowed to just ignore calls because  they think they might be bogus. Having drone overflight before the officers  arrive on scene can help clear those nuisance calls faster and help you get  back to real emergencies.
To be fair, the ACLU report is not coming out against using drones to  improve public safety or even officer safety. It’s biggest concerns are privacy  of individuals who might be surveilled without a warrant. And here is where the  organization’s argument pretty much falls apart. The small rotor driven drones  operated by most law enforcement agencies have an average flight time of 30  minutes. Unless you have a bunch of drones or a bunch of batteries or both, you  are not going to be able to conduct any lengthy surveillance of a location,  group, or individual with untethered police drones. They are best used for taking a quick  peek at something or someone.
The disconnect lies in the fact that much of the public doesn’t realize the  limitations of these aircraft, especially the anti-law enforcement public that  believes John Law can bust them for cocaine possession after looking in their  bedroom window with a DJI Mavic. Another issue is that much of the public  conflates police drones with military drones and thinks they can loiter over  their house for hours on end like a U.S. Air Force Reaper drone.
To its discredit, the ACLU report does not explain this difference or talk  at all about flight times. It even invokes the concern that police would hover  drones over high crime areas. (Not for more than 25 minutes, they wouldn’t. Unless they are using a tether.)  You can draw one of two conclusions from this, either the ACLU is ignorant of  the battery performance of typical quadcopter drones or they strategically left  out this information to fire up the activists against DFR programs. Hint: The  rest of the report is very well researched.
The ACLU is calling on a moratorium for new DFR programs until there is more  information on the existing ones. Here’s all the information they need. Chula  Vista PD and other users of DFR have been remarkably transparent about their  programs. Current battery technology prevents small police drones from being  used for the kinds of privacy violations that the ACLU is worrying about in its  report—and that technology is unlikely to radically improve for a decade or  more. And most importantly, DFR has likely saved police and civilian lives.
DFR programs are a resounding success. And more agencies should launch these  programs once they have constitutionally compliant policies in place, community  support, and funding.
