This article is very light on explaining why this might be necessary for the police.

Does anyone have any suggestions as to why this advice was issued?

Re:Police told not to download NHS Covid-19 app by tgsovlerkhgsel on Monday September 28, 2020 @01:41PM (#24619255)
Could be mistrust about the anonymity properties of the system, but my guess is that they don't want too many officers to be confirmed as contacts, and thus be forced to self-isolate.

If you don't look at the problem, there is no problem!

If you assume that officers are following proper protocols (masks, gloves, proper hygiene) .. then I would say that it makes sense to not quarantine everyone that the officers come in contact with.
Re:Police told not to download NHS Covid-19 app by nostoc on Monday September 28, 2020 @02:04PM (#24619519)
If you assume that everybody follows the proper distancing and wears a mask, we'd have already solved this pandemic 6 months ago.

Assuming people will follow proper protocols, whether they are police officers or not, is not a good plan.

What is the most common way of transmision? I assume not random policemen but relatives and friends. Try doing distancing there.
Re:Police told not to download NHS Covid-19 app by TeMPOraL on Monday September 28, 2020 @03:15PM (#24620256)
The problem is that policemen are well-connected nodes in the transmission graph. Those on fieldwork will meet a lot more random people any given day than you or I will on a shopping run.

I don’t remember anyone saying the pandemic would be solved in a few months if everyone followed proper protocols. It was about flattening the curve, which in fact should increase the length of the pandemic.

China, Taiwan, and a number of other states (many in east / southeast Asia) have effectively contained the virus. China did so in 6--8 weeks.

Western countries notably have not.

Re:Police told not to download NHS Covid-19 app by LudwigNagasena on Monday September 28, 2020 @04:57PM (#24621149)
Well, maybe Western countries should have talked about containing the virus, not flattening the curve.

Indeed it was a massive messaging error. For maybe 20% more short term work we’d be in a new zealand/east asia situation. Summer was the time to do it.

Now we just have hard choices.

Re:Police told not to download NHS Covid-19 app by makomk on Monday September 28, 2020 @05:38PM (#24621501)
At this point, I think it's pretty clear that New Zealand's approach couldn't be expected to lead to New Zealand-style results in places that aren't relatively small islands a thousand miles or so by sea from the nearest neighbour. There are just too many infections that slip through the net even after banning most people from travelling there and requiring returnees to quarantine in state-run facilities at their own expense for two weeks - it works for them, but the same level of per-capita leakage in a country with even ten times the population would cause such a stream of imported cases spreading Covid in the community that I don't think it'd ever be able to drop below level three restrictions, let alone beome Covid-free.

In reality the UK probably wouldn't even be able to manage that - for example, we have a constant stream of lorry drivers coming in from locations throughout Europe to destinations throughout the UK, many of them with absolutely vital goods, and that's a great way to spread Covid from country to country. Somewhere like the US would stand even less chance.

Re:Police told not to download NHS Covid-19 app by graeme on Tuesday September 29, 2020 @09:49AM (#24627767)
I’m originally from eastern canada. They have completely eliminated local transmission. And they have truck drivers bringing in goods, including from the US.

Haven’t heard of it as a source of transmission. Truck drivers generally don’t get off their shift and then go sing karaoke.

And I live now in Quebec, which got local transmission down to almost nothing. But then they opened bars for three months. I think if they had kept them closed a month longer and told the pop “get to zero and we can have a normal winter” we could have done it. Now we’re surging again.

Re:Police told not to download NHS Covid-19 app by LudwigNagasena on Monday September 28, 2020 @07:18PM (#24622309)
There was no messaging error. Everyone was talking about flattening the curve, no one was talking about preventing cases. I wonder where this gaslighting comes from. It seems like we don't even need 1984 agencies to rewrite history, people do it themselves in their heads to keep up with the current agenda...
Re:Police told not to download NHS Covid-19 app by graeme on Tuesday September 29, 2020 @09:46AM (#24627737)
What I mean is a lot of people, like me, said flatten the curve, but would have wanted to eliminate it if it seemed reasonably possible. So I and other people who said the same thing now feel we made an error.

Flatten the curve started as a Twitter meme and only then spread to governments. I don’t think govts wanted to eliminate, but my point is I wish those who were in the forefront had sent a different message. I was looking at this from mid feb, before western governments were generally sending any message at all.

Re:Police told not to download NHS Covid-19 app by pbhjpbhj on Monday September 28, 2020 @05:16PM (#24621314)
Surely they're identical? Flattening the curve means preventing as far as possible further community infections so that the infection rate stays low. Obviously it can't do anything about infections that have already happened, nor about new infections in situations where isolation is beyond practicable.

Containing the virus is the same, preventing ongoing community infections, etc.. Different words for the same overarching activity.

Maybe "containing" would have been a better description, arguably it wouldn't have allowed laxities to be introduced for economic reasons without it being more apparent; which goes against UK governments playbook it seems.

Did any countries public service messaging refer to "containing"?

Re:Police told not to download NHS Covid-19 app by LudwigNagasena on Monday September 28, 2020 @06:20PM (#24621836)
Surely they are two absolutely different things with different goals. Nobody was talking about reducing the total number of cases, where did you get this idea from?

Just look at any article when the idea of “flattening the curve” entered the news, e.g. https://www.nytimes.com/article/flatten-curve-coronavirus.ht...

Drew Harris, a population health analyst at Thomas Jefferson University in Philadelphia that is cited in this NYTimes article, has said:

>Important to remember that #Covid-19 epidemic control measures may only delay cases, not prevent.

and

>Without a vaccine, eventually everyone is likely to be exposed to the virus. Some won't get sick, some will have mild illness, some severe, and a few will die. The goal is to put this off for as long as possible so we have time to prepare and spread out the surge of cases.

Re:Police told not to download NHS Covid-19 app by mytailorisrich on Monday September 28, 2020 @02:15PM (#24619654)
It's reasonable to assume that Police has procedures that are followed, or at least that are followed infinitely better than the general public. And this has also to be balanced with the fact that the Police requires a high level of security (not a good idea for them to be tracked by a third party app).

It's much more important, because much more significant both in term of raw numbers and in term of risk of non compliance, to ensure that the general public follows the same: I was at the supermarket yesterday and the app told me that no less than 5 positive people were inside... with no consequences.

This is not supported by evidence. In other words, the world doesn't function the way we wish it would.

What's your evidence? Because police do have procedures that are internally enforced whereas the general public does not and is not exactly keen on rules (as we've seen)

Sounds like some people are criticising for the sake of it because this is the Police...

Re:Police told not to download NHS Covid-19 app by throw_away on Monday September 28, 2020 @03:49PM (#24620566)
Because the premise I was responding to was "It's reasonable to assume that Police has procedures that are followed, or at least that are followed infinitely better than the general public."

I didn't take that as meaning a specific police force, but rather, police in general. I was specifically responding to mytaylorrsrich's comment that people are reacting negatively to the police just because they are police, whereas my point was that they were believing that the police always held themselves to a higher standard just because they were police. I'm not convinced that is the case, and this link is a point of evidence to that effect.

Re:Police told not to download NHS Covid-19 app by mytailorisrich on Monday September 28, 2020 @05:31PM (#24621433)
The police do have procedures and do behave much better than the general public.

As also repeated the police has extra security constraints, which must be balanced with any benefits the tracking app bring. Clearly they think that allowing a third party app which goal is real-time tracking, on police phones has more downsides than upsides.

I don't know anything about American police and I don't care. This is not the topic of the discussion, which is about an UK tracking app and UK police forces.

I do think that shooting this advice against installing the app (on police phones) and my comments down is largely being obtuse because it's the police or because they don't want to acknowledge the specificities of police work.

And we might as well assume the sun rises in the west.

Saturday I saw a hospital worker (role unknown) with his mask in his hand. Not only that, but he was heading into the bathroom--a place you should be extra cautious about.

Other than that I have seen very good compliance by all medically trained people in healthcare facilities, sloppy compliance by those without medical training (receptionists etc.) I rather suspect he was not actually a medical worker despite being in the treatment area.

Re:Police told not to download NHS Covid-19 app by craftinator on Monday September 28, 2020 @02:36PM (#24619876)

English hospitals already run out of tests a few times this year and people are going to Scottish hospitals to take tests. People in Wales are told to go to Scotland to take tests after being in contact with infected. Problem solved itself many times.
Re:Police told not to download NHS Covid-19 app by winphone1974 on Monday September 28, 2020 @01:45PM (#24619297)
My guess is that contact times and distances are targeting unprotected citizens in their day to day. Police interact with a much more at risk target demographic but with better protection, protocols and awareness. This lack of calibration would probably trigger way more false positives
Re:Police told not to download NHS Covid-19 app by iainmerrick on Monday September 28, 2020 @07:13PM (#24622258)
better protection, protocols and awareness

What do you base that on? I don’t think the police are wearing masks at any greater rate than any other profession, for example. What makes them less at risk?

I’d assume that police are being neither more nor less cautious than anyone else, on average, and are at relatively high risk just due to the nature of their jobs. If so it would be beneficial to the police and to everyone else for the police to use COVID contact tracing apps.

This seems plausible.

I'm not sure how frequently the codes are refreshed, but you could just hide a bluetooth receiver near the police station to get the daily codes for most officers, transmit that to your phone and have an app that tells you if a police officer is nearby.

The tracing app itself will only tell you that but you can receive the BLE signals with other bluetooth sniffer apps.

Re:Police told not to download NHS Covid-19 app by dividuum on Monday September 28, 2020 @05:28PM (#24621410)
A bit of background. Every app that is intended to be actually used by a people essentially must use the framework included in the OS. Otherwise it would run into various roadblocks like not being able to properly run in the background or not having the required BLE access. So that leaves you with using the cross platform exposure notification frameworks on both iOS and Android. The way those work well documented https://covid19.apple.com/contacttracing. The "Temporary Expose Key" (TEK) changes exactly every 10 minutes. How often the BLE MAC changes depends on the OS, but that's around 10-20 minutes. As you have to change both "fingerprints" at the same time to prevent tracking across individual changes (See also [1]), in practice the sent TEK is changed at the BLE MAC change interval. So that's where to 10-20 minutes come from.

[1] A mostly theoretical flaw (as you need a large network of BLE scanners) on some devices: https://hackaday.com/2020/09/03/covid-tracing-framework-priv...

Re:Police told not to download NHS Covid-19 app by ampersandy on Monday September 28, 2020 @01:06PM (#24618841)
My first thought is that police policy may require security audits/etc. before they have any location tracking software installed on their phones that may potentially be abused to know the location of police.
Re:Police told not to download NHS Covid-19 app by dividuum on Monday September 28, 2020 @05:33PM (#24621450)
Any app using the Expose notification framework is explicitly forbidden from accessing any kind of location information, either GPS or otherwise. See https://blog.google/documents/72/Exposure_Notifications_Serv... (3 c i) and https://developer.apple.com/contact/request/download/Exposur... (3.3)

The police ‘has better protection’, ‘knows better’ or whatever excuse they come up with. In the end it’s just that, rules are for plebs, not for the police.

Re:Police told not to download NHS Covid-19 app by drcongo on Monday September 28, 2020 @01:07PM (#24618859)
I'm guessing it's because they come into contact with so many people every day. Especially those policing the recent anti-mask "protests" in Trafalgar Square. Half the force would be self-isolating at any given time.

However, it's just as likely that the app is spyware given that it doesn't, and can't link with any COVID tests you have via the NHS, only those done by Serco.

They've changed it now so it should now be possible to let most tests performed by a public health authority or an nhs lab be reported on the app.

This seems like the equivalent of saying that we can't have carbon monoxide alarms in this building because they keep going off.

Re:Police told not to download NHS Covid-19 app by makomk on Monday September 28, 2020 @02:49PM (#24620007)
The app has inherently limited accuracy and I think the algorithm it's using would likely flag anyone who goes anywhere near an event where a large number of people end up testing positive. It can't really tell the difference between, say, people attending a mass superspreading rave and mingling with contagious attendees with no protection, and police officers in PPE rounding up attendees who've been infected at the event but aren't contagious yet. It's just a fundamental limitation of using an automated app. This probably isn't a huge problem most of the time, but it seems like police using the app could rapidly deplete the ability to actually enforce Covid restrictions.
Re:Police told not to download NHS Covid-19 app by TeMPOraL on Monday September 28, 2020 @03:19PM (#24620288)
Couldn't the officers just ignore the app recommendation, but still use it? If they don't use it at all, they become breaks in the transmission graph.

In other words: if I was infected and attended a rave, a policeman interacted with me, and you interacted with that policeman two days later, you'd probably want to know about that fact and consider self-quarantining.

Re:Police told not to download NHS Covid-19 app by winphone1974 on Monday September 28, 2020 @01:47PM (#24619324)
Yes, but I would hope that police are more aware of the situation and taking protective measures compared with say 2 people getting together for coffee. If this is the case the definition of contact needs to be different

> This seems like the equivalent of saying that we can't have carbon monoxide alarms in this building because they keep going off.

The comparison works if you add that the building is always filled with CO and that this is a known fact and that people in it are pros and take the appropriate measures. In such case, CO alarms are just noise.

Police evolve in a high risk environment and have procedure against that. Because of that and the security requirements of the Police, it has simply been concluded that the downsides of installing a third party tracker on a police phone outweighed the upsides.
