They began as tools in military combat. Now aerial drones
are being considered by Bay Area law enforcement agencies as a cost-cutting way
to replace helicopters, and use technology to fight crime and save lives.
Alameda County Sheriff Greg Ahern first tested one of these
Unmanned Aerial Systems or UAS about a year ago. Now he’s looking into possibly
bringing a drone here. His office would be the first in California to do it.
Armed with live-video-feeding capabilities and different features, like infrared
devices, these drones can cost in the ballpark of 50- to 100-thousand dollars or
more.
There are several different models, but the one Ahern is
considering weighs four pounds and spans four-feet. He says the drones get a
birds-eye view that most tactical officers on the ground would never get,
sometimes endangering their lives. A demonstration at the county’s Office of
Emergency Services building in Dublin a couple months ago featured a man
standing in the shadows on a rooftop, with three possible explosives clearly in
his reach. The drone saw everything; the officers on the ground could not.
“Very valuable to any tactical officer, as you’re setting up
your perimeters and knowing what the suspect may have in his hands, how the
suspect is dressed, what are the avenues of escape?” Ahern added that his office
would only use drones during emergencies, from a high-speed or high-risk chase
to search-and-rescue operations in disasters, as well as proactive policing
measures like catching marijuana grows in fields on public lands and in grow
houses.
But not everyone is pleased at the growing number of agencies
looking to use these UAS. The American Civil Liberties Union or ACLU says drones
should only be deployed when a warrant for a specific crime is involved. The
ACLU is also worried that they may harm both privacy and people. In a statement,
the ACLU wrote, “Drone manufacturers are also considering offering police the
option of arming these remote-controlled aircraft with weapons like rubber
bullets, Tasers, and tear gas.”
Sheriff Ahern says an armed drone is out of the question. He
says local public safety agencies must take advantage of innovation that’s out
there, calling it a “no brainer.”
In two weeks, the Alameda County Sheriff’s Office is hosting
its annual “Urban Shield” preparedness exercise involving about 30 other law
enforcement agencies. That’s where they’ll get the chance to test out different
drones in simulations of disasters and high-risk situations to see if they
really work. If so, Sheriff Ahern says he has been looking specifically into a
federal grant that promotes community policing.
