Why police forces need to be honest regarding mass mobile phone surveillance
Police
forces across the UK are covering up their use of sophisticated mass
surveillance devices, known as IMSI-catchers. The tools on offer vary – from
in-the-field technology that can hack mobile phones, to facial recognition and
predictive policing capabilities. This technological revolution is granting
police unprecedented access to people’s lives. Investigations by The
Bristol Cable have revealed that at least nine police
forces in the UK have secretly purchased mobile phone surveillance devices,
known as IMSI-catchers. These indiscriminate
surveillance tools allow police to track mobile phone locations and identities
in real time, to intercept text messages and calls across a large radius.
According to some manufacturers’ catalogues, IMSI-catchers can hack up to 1,500 handsets per minute across
five networks within 8km2 of their deployment.
At least 197
parliamentary constituencies are policed by the nine constabularies known
to possess IMSI-catchers. This information only came to light after police
procurement data and documents were analysed by The Bristol Cable. The
investigation showed that constabularies had spent hundreds of thousands of
pounds (over £1m by the Metropolitan Police alone) on IMSI-catchers, and that
they were using an acronym – CCDC (covert communications data capture) – to
disguise their purchases. To date, the Home
Office and individual police forces have pursued a policy of neither confirming
nor denying the possession or use of IMSI-catchers. Public authorities and
ministers have consistently refused to declare whether police or other agencies
possess or operate the technology, despite mounting evidence that its use is
becoming widespread.
Police stonewall on mobile phone surveillance
Constabularies have
denied freedom of information (FoI) requests, but they have gone further to
stifle public debate. Police and crime commissioners have a legal duty to
publish spending reports monthly for their respective forces, but in the months
following the initial investigation, 30 police forces temporarily stopped
publishing monthly spending data giving details of the contracts they award,
and have since revised what information is published. In the case of Avon
and Somerset Constabulary, the police and crime commissioner openly stated that
the spending data had been taken down from its website and redacted in the
interests of “national security” in response to the investigation. This
stonewalling suggests that neither journalistic inquiry nor freedom of
information requests by concerned citizens will, on their own, open the door to
transparency. Consequently, The Bristol Cable took the
decision to turn its investigation into a national
campaign to press for change.
The campaign seeks
clarity to some fundamental questions:
· In what
circumstances are IMSI-catchers used?
· Which authorities
operate them?
· How are innocent
people safeguarded from this intrusive surveillance technology?
A 2016
investigation by technologist Richard Tynan found evidence of the use of
IMSI-catchers in London, including at a large, public, anti-austerity
demonstration and outside the Houses of Parliament. The charity Liberty has
expressed concern that IMSI-catchers could be being used to target protestors,
particular communities and places of worship.
Government silent on mobile phone monitoring
The indiscriminate,
dragnet nature of IMSI-catcher technology, which intercepts the data of all
mobile phones within an area of several kilometres, is unlikely to be
proportionate or justifiable in law. It is therefore concerning that Parliament
has not been consulted on the use of IMSI-catchers and that relevant
statistical data or governing policies have not been published.
A parliamentary briefing by The
Bristol Cable – with guest contributions from Angela Patrick,
barrister at Doughty Street Chambers, and Silkie Carlo, then advocacy officer
at Liberty (now at Big Brother Watch) – lays out the uncertain legal basis
for the use of IMSI-catchers and the need for urgent transparency. Thangam
Debonnaire, MP for Bristol West, has submitted written questions to the Home
Office seeking clarity on which forces own and operate IMSI-catchers and what
guidance governs their use. The response was
vague and shed nothing new. Nick Hurd MP referenced the Police Act 1997 and the
Intelligence Services Act 1994 as the relevant governing legislation, and the
investigatory powers commissioner as tasked with oversight. However, Hurd
failed to confirm the technology’s mere existence, or to specify which forces
owned or operated it.
With crime growing
increasingly sophisticated, police are turning to innovative technology. But
can the police and security services legitimately stay silent about their
capabilities by claiming transparency will harm operations? Internationally,
IMSI-catchers have already been dubbed “law enforcement’s worst-kept secret”. In
recent years, there have been a string of damning revelations about illegal or
controversial police surveillance powers, with police spying infringing the
civil liberties of journalists, parliamentarians and campaigners.
Definition of serious crime is too broad
These cases have
also raised concerns over how IMSI-catchers could be misused. And yet, the
issue here is less of police misconduct. Rather, the primary issue is one of a
turbulent political climate changing the legislative definitions of extremism
and serious crimes, which surveillance capabilities only enhance. Take the Investigatory Powers Act (IPA), also
known as the snoopers’ charter. It limits surveillance by
police and government agencies to “serious” crimes. However, Angela Patrick
writes in the parliamentary briefing that these crimes are “broadly defined to
include offences carrying a sentence of over three years’ imprisonment, or any
violent crime or crimes done for unspecified ‘substantial’ financial gain or
where conduct is by a large number of persons in pursuit of a common purpose”.
Patrick highlights
that group conduct is covered, meaning that police and agencies might seek to
rely on these powers for the investigation of public order offences arising
from protest activities. Meanwhile, any investigation of violent crime or
financial crime for “substantial gain” will also open the door to the IPA. This
threshold is less stringent than it might first appear, placing only limited
restraint on state surveillance.” With the goalposts of justice in flux, one cannot be confident that
institutionalised checks and balances will protect civil liberties. As Cardinal
Richelieu, the 16th century French clergyman, incisively wrote: “If one would
give me six lines written by the hand of the most honest man, I would find
something in them to have him hanged.”
