The shocking police
crackdown
on protestors in Missouri,
in the wake of the police
shooting of Michael Brown,
underscored the extent to which advanced
military weapons and equipment,
designed for the battlefield,
are making their way
to small town police departments
across the United States.
Although much tougher to observe,
this same thing is happening
with surveillance equipment.
NSA-style mass
surveillance is enabling
local police departments
to gather vast quantities
of sensitive informaiton
about each and every one of us
that was never previously possible.
Location information can
be very sensitive.
If you drive your car around
the United States,
it can reveal if you go
to a therapist,
or an Alcoholic Anonymous meeting,
if you go to church
or if you don't go to church.
And when that
information about you
is combined with the same
information
about everyone else,
the government can gain a
detailed portrait
of how private citizens act.
This information used to be private.
Thanks to modern technology,
the government knows far too much
about what happens
behind closed doors.
And local police departments
make decisions
about who they
think you are
based on this information.
One of the key technologies
driving mass location tracking
is the innocuous-sounding
automatic license plate reader.
if you haven't seen one,
it's probably because you didn't
know what to look for
--they're everywhere.
Mounted on roads or
on police cars,
automatic license plate readers
capture images of every passing car
and convert the license plate
into machine-readable text
so that they can be checked
against hot lists
of cars potentially wanted
for wrongdoing.
But more than that, increasingly,
local police departments are
keeping records not just
of people wanted
for wrongdoing,
but every plate that
passes them by,
resulting in the collection
of mass quantities of data
about where Americans have gone.
Did you know this was happening?
When Mike Katz-Lacabe asked
his local police department
for information about the plate
reader data they had on him.
This is what they got:
in addition to the date,
time and location,
the police department had
photographs that captured
where he was going and
often, who he was with.
The second photo
from the top
is a photo of Mike and
his two duaghters
getting out of their car
in their own driveway.
The government has
hundreds of photos like this
of Mike going about his
daily life.
And if you drive a car
in the United States,
you can bet money
that they have photographs
like this of you going
about your daily life.
Mike hasn't done
anything wrong,
Why is it okay that
the government
is keeping all of this information?
The reason it's happening
is because as the cost of storing
this data has plummeted,
the police department
simply hangs on to it,
just in case it could be
useful someday.
The issue is not just that
one police department
is gathering this information
in isolation,
or even that multiple police
departments are doing it.
At the same time,
the federal government
is collecting all of these
individual pots of data,
pooling them together into
one vast database
with hundreds and
millions of hits
showing where Americans
have traveled.
This document from the
Federal Drug Enforcement Administration,
which is one of the agencies
primarily interested in this,
is one of several that reveal
the existence of this database.
Meanwhile, in New York City,
the NYPD has driven police cars
equipped with license plate readers
past mosques in order to
figure out who is attending.
The uses and abuses
of this technology
aren't limited to the United States.
In the UK, the police deparmtnet
put 80-year-old John Kat
on a plate reader watch list
after he had attended
lawful political demonstrations
where he liked to sit on a bench
and sketch the attendees/
license plate readers aren't the
only mass location tracking technology
available to law enforcement
agents today.
Through a technique known as
a cell tower dump,
law enforcement agents can
uncover who was using
one or more cellphones
at a particular time,
a technique that is
known to reveal
their location of
tens of thousands
and even hundreds
of thousands of people.
Also, using a device
known as a Sting Ray,
law enforcement agents
can send tracking signals
inside people's houses
to identify the cell phones located there.
And if they don't know
which house to target,
they've been known to drive
this technology through entire
neighborhoods.
Just as the police in Ferguson possess
high-tech weapons and equipment,
so too do police departments across
the United States possess
high-tech surveillance gear.
Just because we don't see it,
doesn't mean it's not there.
The question is, what should
we do about this?
I think this poses a serious
civil liberties threat.
History has shown that once
the police have massive
quantities of data
tracking the movements
of innocent people,
it gets abused, maybe for
blackmail,
maybe for political advantage,
maybe for simple voyeurism.
Fortunately, there are
steps we can take.
Local police departments can
be governed by the city councils,
which can pass laws
requiring the police
to dispose of the data of
innocent people
while allowing the legitimate
uses of the technology
to go forward.
Thank you.
