Met Police chief backs legislative framework for police tech

Metropolitan Police commissioner Cressida Dick has referred to as on the federal government to introduce an “enabling legislative framework” to stipulate how police ought to or mustn’t use rising applied sciences.

Dick’s feedback had been made on the Royal United Services Institute (Rusi) on 24 January throughout the launch of the safety suppose tank’s newest report on police algorithms.

The report discovered that new nationwide steerage was wanted “as a matter of urgency” to make sure police algorithms are deployed in lawful and moral methods.

“We are a law enforcement organisation, it is our duty to uphold the law – give us the law and we’ll work within it,” mentioned Dick.

“In the meantime, my colleagues and I will continue to take a keen interest in considering how best to use new technology in an effective, ethical and proportionate way.”

Dick welcomed the authorities’s 2019 normal election pledge to “empower the police to safely use new technologies like biometrics, AI and the use of DNA within a strict legal framework”, including that any future pointers must be clear, easy and match for the 21st century – that means they should be adaptable to a fast-moving technological panorama.

“I strongly believe that if we in the UK can get this right, we stand in good stead to be world leaders in appropriate, proportionate tech-enabled human policing,” mentioned Dick.

On the “tech-enabled human policing approach”, Dick mentioned that it was higher to consider “augmented intelligence” reasonably than synthetic intelligence.

“The term describes better how technology can work to improve human intelligence rather than to replace it. That feels much closer to how we in policing are using technology,” she mentioned.

“That points to tools that are there to aid police officers rather than replace them – to augment their decision-making rather than to take the final decision for them.”

Giving the Metropolitan Police Services’ (MPS) trials of reside facial recognition (LFR) expertise for instance of augmented intelligence, Dick mentioned that they resulted within the arrest of eight people that may “probably not have been arrested” in any other case.

“This is about a tool that can augment intelligence rather than replace it,” she mentioned, including that human officers will at all times make the ultimate resolution about whether or not to intervene or not if the LFR expertise finds a match.

“The only people who benefit from us not using [technology] lawfully and proportionately are the criminals, the rapists, the terrorists, and all those who want to harm you, your family and friends,” she mentioned.

LFR already operational

Despite Dick calling for a legislative framework to control the police’s use of algorithmic applied sciences, the Metropolitan Police started deploying LFR operationally for the primary time in February 2020 within the absence of nationwide steerage and regardless of earlier requires it.

In October 2019, for instance, following a 17-month investigation into police forces’ use of LFR, the Information Commissioner’s Office (ICO) advisable that the federal government introduce a statutory and binding code of observe on its deployment.

“I would argue that most areas in which we are already using modern technology are largely uncontroversial to the public,” mentioned Dick, earlier than trying to dispel “some current and apparently pervasive myths” concerning the Metropolitan Police’s use of LFR.

Dick claimed there’s a “very strong” authorized foundation for LFR use by police and that human officers will at all times make the ultimate resolution.

On the MPS web site, the power lists the legal guidelines and laws it claims allows it to make use of LFR, which incorporates the Human Rights Act 1998 and the Data Protection Act 2018 amongst others.

However, based on a July 2019 report from the Human Rights, Big Data & Technology Project, primarily based on the University of Essex Human Rights Centre, it’s extremely attainable that police deployment of LFR could also be held illegal if challenged in courtroom as a result of “no explicit legal basis exists authorising” its use.

It concludes the “implicit legal authorisation claimed by the MPS… is likely inadequate when compared with the ‘in accordance with the law’ requirement established under human rights law”.

The report, which marks the primary impartial evaluate of the MPS LFR trials, additionally highlighted a discernible “presumption to intervene”, that means it was normal observe for officers to interact a matched particular person.

Dick additionally claimed that the expertise utilized by the MPS is confirmed to not have an “ethnic bias”, including the one bias is that “it is slightly harder to identify a wanted women than a wanted man.”

This is regardless of the very fact the MPS’ facial recognition software program, which is supplied by Japan’s NEC Corporation, has by no means undergone any demographic testing.

On prime of this, quite a few research exist pointing to a racial bias in related facial recognition software program. In the UK particularly, black individuals are thrice extra more likely to be arrested than white folks, based on the federal government’s most up-to-date statistics, however no extra more likely to be convicted.

The similar is true of individuals with combined ethnicity, who’re greater than twice as more likely to be arrested than white folks.

In March 2019, the Science and Technology Committee heard there are greater than 23 million custody pictures on the Police National Database (PND), no matter whether or not the particular person was subsequently convicted or not.

This recommend that, given these custody pictures are used to create LFR “watchlists”, harmless folks of color are much more more likely to be scanned, and subsequently engaged by police, than harmless white folks.

In May 2019, the BBC reported that the MPS missed not less than three possibilities to evaluate how effectively the programs take care of ethnicity over the previous 5 years.
