COVID-19 has shone a very bright light on the importance of widely available, affordable broadband. Nearly 42 million Americans lack access to any broadband whatsoever--double FCC estimates. And millions more can't afford service thanks to a lack of competition among very powerful, government pampered telecom monopolies.

As usual, with political pressure mounting to "do something," DC's solution is going to be to throw more money at the problem:

"The plan unveiled Thursday would inject $80 billion over five years into expansion of broadband infrastructure into neglected rural, suburban and urban areas, with an emphasis on communities with high levels of poverty. It includes measures to promote rapid building of internet systems, such as low-interest financing for infrastructure projects."

To be clear, subsidies often do help shore up broadband availability at coverage. The problem is that the United States government, largely captured by telecom giants with a vested interest in protecting regional monopolies, utterly sucks at it.

Despite ample pretense to the contrary, nobody in the US government actually knows where broadband is currently available. Data supplied by ISPs has never been rigorously fact-checked by a government fearful of upsetting deep-pocketed campaign contributors (and valued NSA partners). As a result, our very expensive ($350 million at last count) FCC broadband coverage map creates a picture of availability and speed that's complete fantasy. It's theater designed to disguise the fact that US broadband is mediocre on every broadband metric that matters. Especially cost.

While there has been some effort to fix the mapping problem via recent legislation, the FCC still needs several years (and more money) to do so. And while you'd think this would be more obvious, you can't fix a problem you can't even effectively measure. There's also not much indication that the $80 billion, while potentially well intentioned, would actually get where it needs to go. Especially right now, when federal oversight is effectively nonexistent.

You may or may not have noticed this, but US telecom is a corrupt, monopolized mess. Giants like AT&T and Comcast all but own state and federal legislatures and, in many instances, literally write the law. Feckless regulators bend over backward to avoid upsetting deep-pocketed campaign contributors. So when subsidies are doled out, they very often don't end up where regulators and lawmakers intended. There's an endless ocean of examples where these giants took billions in taxpayer subsidies to deploy fiber networks that are never fully delivered.

If you were to do meaningful audit (which we've never done because again we're not willing to adequately track the problem or stand up to dominant incumbent corporations) you'd very likely find that American taxpayers already paid for fiber to every home several times over.

That's not to say is that there aren't things Congress could do to help the disconnected during COVID-19. Libraries for example have been begging the FCC for the ability to offer expanded WiFi hotspot access (via mobile school buses) to disconnected communities without running afoul of FCC ERate rules. But while the FCC said libraries can leave existing WiFi on without penalty, it has been mute about whether they can extend coverage outside of library property. Why? As a captured agency, the FCC doesn't like anything that could potentially result in Comcast or AT&T making less money.

None of this is to say that we shouldn't subsidize broadband deployment once we get a handle on the mapping problem. But it's a fantasy to think we're going to immediately fix a 30 year old problem with an additional $80 billion in a mad dash during a pandemic. US broadband dysfunction was built up over decades. It's the product of corruption and rot that COVID-19 is exposing at every level of the US government. The only way to fix it is to stand up to industry, initiate meaningful reform, adopt policies that drive competition to market, and jettison feckless lawmakers and regulators whose dominant motivation is in protecting AT&T, Verizon, Comcast, and Spectrum revenues.

Maybe the pandemic finally provides the incentive to actually do that, but until the US does, these subsidization efforts are largely theater.

A couple of months ago, a records request revealed a private surveillance contractor had access to nearly every piece of surveillance equipment owned and operated by the state of Utah. Banjo was the company with its pens in all of the state's ink. Banjo's algorithm ran on top of Utah's surveillance gear: CCTV systems, 911 services, location data for government vehicles, and thousands of traffic cameras.

All of this was run through Banjo's servers, which are conveniently located in Utah government buildings. Banjo's offering is of the predictive policing variety. The CEO claims its software can "find crime" without any collateral damage to privacy. This claim is based on the "anonymization" of harvested data -- a term that is essentially meaningless once enough data is collected.

This partnership is now on the rocks, thanks to an investigation by Matt Stroud and OneZero. Banjo's CEO, Damien Patton, apparently spent a lot of his formative years hanging around with white supremacists while committing crimes.

In grand jury testimony that ultimately led to the conviction of two of his associates, Patton revealed that, as a 17-year-old, he was involved with the Dixie Knights of the Ku Klux Klan. On the evening of June 9, 1990 — a month before Patton turned 18 — Patton and a Klan leader took a semi-automatic TEC-9 pistol and drove to a synagogue in a Nashville suburb. With Patton at the wheel, the Ku Klux Klan member fired onto the synagogue, destroying a street-facing window and spraying bullets and shattered glass near the building’s administrative offices, which were next to that of the congregation’s rabbi. No one was struck or killed in the shooting. Afterward, Patton hid on the grounds of a white supremacist paramilitary training camp under construction before fleeing the state with the help of a second Klan member.

If you're wondering where the state of Utah's due diligence is in all of this, there's a partial explanation for this lapse: the feds, who brought Patton in, screwed up on their paperwork.

Because Patton’s name was misspelled in the initial affidavit of probable cause filed in Brown’s case — an FBI agent apparently spelled Damien with an “o” rather than an “e” — any search of a federal criminal court database for “Damien Patton” would not have surfaced the affidavit.

Now that his past has been exposed, the state of Utah has announced it won't be working with Banjo.

The Utah attorney general’s office will suspend use of a massive surveillance system after a news report showed that the founder of the company behind the effort was once an active participant in a white supremacist group and was involved in the shooting of a synagogue.

The AG's office can only shut down so much of Banjo's surveillance software. Other government agencies not directly controlled by the state AG are making their own judgment calls. The University of Utah is suspending its contract with Banjo, but the state's Department of Public Safety has only gone so far as to "launch a review" of its partnership with the company. City agencies and a number of police departments who have contracts with Banjo have yet to state whether they will be terminating theirs.

And the AG's reaction isn't a ban. The office appears to believe it might be able to work through this.

“While we believe Mr. Patton’s remorse is sincere and believe people can change, we feel it’s best to suspend use of Banjo technology by the Utah attorney general’s office while we implement a third-party audit and advisory committee to address issues like data privacy and possible bias,” Piatt said. “We recommend other state agencies do the same.”

It's refreshing to hear a prosecutor state that it's possible for former criminals to turn their lives around and become positive additions to their communities, but one gets the feeling this sort of forgiveness is only extended to ex-cons who have something to offer law enforcement agencies. Everyone else is just their rap sheet for forever, no matter how many years it's been since their last arrest.

The other problem here is the DA's office's tacit admission it did not take data privacy or possible bias into account before granting Banjo access to the state's surveillance equipment, allowing it to set up servers in government buildings, and giving it free rein to dust everything with its unaudited AI pixie dust.

These are all steps that should have taken place before any of this was implemented, even if the state had chosen to do business with a company with a less controversial CEO. This immediate reaction is the right step to take, but a little proactivity now and then would be a welcome change.

The coronavirus pandemic and its associated lockdown in most countries has forced major changes in the way people live, work and study. Online learning is now routine for many, and is largely unproblematic, not least because it has been used for many years. However, online testing is more tricky, since there is a concern by many teachers that students might use their isolated situation to cheat during exams. One person's problem is another person's opportunity, and there are a number of proctoring services that claim to stop or at least minimize cheating during online tests. One thing they have in common is that they tend to be intrusive, and show little respect for the privacy of the people they monitor.

As an article in The Verge explains, some employ humans to watch over students using Zoom video calls. That's reasonably close to a traditional setup, where a teacher or proctor watches students in an exam hall. But there are also webcam-based automated approaches, as explored by Vox:

For instance, Examity also uses AI to verify students' identities, analyze their keystrokes, and, of course, ensure they're not cheating. Proctorio uses artificial intelligence to conduct gaze detection, which tracks whether a student is looking away from their screens.

It's not just in the US that these extreme surveillance methods are being adopted. In France, the University of Rennes 1 is using a system called Managexam, which adds a few extra features: the ability to detect "inappropriate" Internet searches by the student, the use of a second screen, or the presence of another person in the room (original in French). The Vox articles notes that even when these systems are deployed, students still try to cheat using new tricks, and the anti-cheating services try to stop them doing so:

it's easy to find online tips and tricks for duping remote proctoring services. Some suggest hiding notes underneath the view of the camera or setting up a secret laptop. It's also easy for these remote proctoring services to find out about these cheating methods, so they're constantly coming up with countermeasures. On its website, Proctorio even has a job listing for a "professional cheater" to test its system. The contract position pays between $10,000 and $20,000 a year.

As the arms race between students and proctoring services escalates, it's surely time to ask whether the problem isn't people cheating, but the use of old-style, analog testing formats in a world that has been forced by the coronavirus pandemic to move to a completely digital approach. Rather than spending so much time, effort and money on trying to stop students from cheating, maybe we need to come up with new ways of measuring what they have learnt and understood -- ones that are not immune to cheating, but where cheating has no meaning. Obvious options include "open book" exams, where students can use whatever resources they like, or even abolishing formal exams completely, and opting for continuous assessment. Since the lockdown has forced educational establishments to re-invent teaching, isn't it time they re-invented exams too?
