The Portland PD has a new tracking toy that has become wildly popular across the country, Automated License Plate cameras that can read (and recognize) all license plates of cars that happen to pass by the camera. See a video of it
here. They can be mounted on patrol cars (Portland has 16 car mounted ones) or at intersections, and they automatically make a record of all license plates whizzing by.
The PD says they can recover stolen cars in an instant if one passes by the Police Cruiser, which is a good thing, but what happens if you are going about your business and your plate gets captured? They keep it on record for
4 years, that's what. This is a lot like the NSA keeping all phone records, and just as personal. Here is a
link to their policy on these creepy things. The
ACLU doesn't like them much either.
Automatic license plate readers have
the potential to create permanent records of virtually everywhere any of
us has driven, radically transforming the consequences of leaving home
to pursue private life, and opening up many opportunities for abuse. The
tracking of people’s location constitutes a significant invasion of
privacy, which can reveal many things about their lives, such as what
friends, doctors, protests, political events, or churches a person may
visit.
In our society, it is a core principle that the government does not
invade people’s privacy and collect information about citizens’ innocent
activities just in case they do something wrong. Clear regulations must
be put in place to keep the government from tracking our movements on a
massive scale.
As the technology spreads, the
ACLU calls for the adoption of legislation and law enforcement agency
policies adhering to the following principles:
License plate readers may be used by law enforcement agencies only
to investigate hits and in other circumstances in which law enforcement
agents reasonably believe that the plate data are relevant to an
ongoing criminal investigation.
The government must not store data about innocent people
for any lengthy period. Unless plate data has been flagged, retention
periods should be measured in days or weeks, not months and certainly
not years.
People should be able to find out if plate data of vehicles registered to them are contained in a law enforcement agency’s database.
Law enforcement agencies should not share license plate reader data
with third parties that do not follow proper retention and access
principles. They should also be transparent regarding with whom they
share license plate reader data.
Any entity that uses license plate readers should be required to report its usage publicly on at least an annual basis.
