Column: Have you triggered the US deportation algorithm on Twitter?

Image: Martin Keene/PA Wire

TODAY, MANY COMPANIES are in the business of monitoring social networks like Facebook and Twitter. Marketers and brand managers gather data and run “sentiment analysis” to see how people are, say, feeling about Coca Cola today. At NewsWhip, we monitor Twitter and Facebook to spot the fastest spreading news stories.

Now the US Federal Government has launched its own social media monitoring strategy. And on Monday we saw some of the results of this strategy, as a pair of tourists were arrested in the US on terror charges over jokes they made on Twitter.

A quick recap: the Daily Mail reports that two tourists, Leigh Van Bryan (from Ireland), and Emily Banting (a British woman) were detained by armed guards last week in LA Airport just after clearing immigration. The duo were separated and interrogated for five hours, and Leigh was transported, in a cage (where he had a panic attack), to a cell, where he held overnight in a cell in the company of Mexican drug dealers. The duo were refused entry to the US and forced to buy new flights back to Europe.

Their offense? In the weeks before his trip, Leigh had joked about his upcoming trip to LA on Twitter, saying he would be “diggin’ Marilyn Monroe up!” (a reference to a Family Guy joke). He also asked a friend on Twitter if they were “free for a quick gossip/prep before I go to destroy America? x”

After his arrest Leigh and Emily tried to explain how both of the tweets were jokes. Going to “destroy” a place means you get drunk and careless there in British slang. Digging up Marilyn Monroe was a reference to a gag from Family Guy, an American TV show. The explanations were ignored as the duo were arrested, processed, and packed off to Europe.

So how did this happen? Here’s where it really gets interesting. And, well, scary.

Twitter as Big Brother?

First, how did the Department of Homeland Security (the DHS, the guys responsible for the border) find Leigh and Emily? It’s unlikely that either of these guys were on “watch lists” in advance of Leigh’s tweets. I mean, look at them. And the “documents” provided to Leigh after his arrest by the DHS officers mentions only his posts on “tweeter” as the cause for refusal of admission. Though it’s possible they had other reasons, none were mentioned by the DHS officers.

So assuming Leigh was not pre-identified before his fatal tweets, the DHS must have picked him out of the 250 million tweets published each day on Twitter, known in the industry as the “firehose”.

How is this accomplished? Well, automated processes – like search terms – will be at work, spotting phrases like “kill” “shoot” “destroy”, etc., when those words appear in tweets with words like America or the US.

This is the same process that brands monitor for things like “I hate Coca Cola” or “I love Coca Cola”. In Boolean search terms, the query will look like: (“hate” or “despise” or “disappoint!” or “love” or “like” or “yummy”) w/3 (“Coke” or “Cola” or “Coca”). This will spot various emotive words appearing close to Coca Cola keywords and give a fuzzy picture of how people feel about Coke today.

The DHS probably has something similar, with a huge range of word searches that someone decided should trigger security alerts, like attack, kill, destroy, etc. (You can probably think of more, but I don’t want to trigger alarm bells by stuffing them all into this post.) When those searches are triggered, then the process begins. Last week, that process culminated quite smoothly in Leigh and Emily’s arrest.

So it seems likely that all of Twitter (and probably Facebook) is being monitored for potential threats, and goodness knows what else. So if you’ve tweeted the word “ridiculous” or “Osama” or “destroy” within a few words of “America”, you might be on a watch list too.

Think you’re safe? If you’re a photographer, what if you’ve tweet that you’re planning to “shoot the Empire State Building”? Or if you’re hoping your product really takes off at a conference, what if you hope it “explodes”? What happens if you tweet that you hope the “US gets wiped out” in the Hockey finals? Or if Mastercard want to “attack” American’s Express’s dominance of the corporate cards market in New York?

Well tough luck. With any of those phrases you may have triggered the “deportation algorithm” – the unfortunate combination of words that makes you look vaguely like a threat to a computer in Arlington, Virgina, and results in your eventual forced removal from the USA.

Fascinating, no? The number of false positives a system like that could throw up is huge. Imagine how many potential terrorist suspects the DHS will discover if “Romney destroys Obama” in a debate? Will the resulting chatter be interpreted as millions of death threats?

Also, how do you feel when you are at a border about having to answer questions about everything you’ve ever said publicly on Twitter or Facebook, when the questioners refuse to understand your answers and will deliberately fixate on the worst possible interpretation of what you said?

What’s the upshot? If you are an “alien” (the US government term for non-US nationals) and if you ever intend on visiting America, it looks like you need to be very careful what you tweet. Or share on Facebook. Or even write online. A joke, political comment, expression of disagreement with an act by a US politician, or anything else might one day get you caged, put in a cell, and effectively “deported” at your own expense, likely never to be allowed to return.

And “aliens” don’t have constitutional rights against the DHS, so you can forget about those “freedom of expression” arguments bubbling up in your mind. So what will you do? Self-censor in case you ever want to go shopping in New York, attend a conference in Vegas, or ski in Colorado? Parse every word you utter online carefully with a view to having to justify it one day to a stern prosecutor who won’t listen to any contextual explanation?

What happened to the Humans?

The DHS has a very sensitive detection social media detection algorithm. In a sense, that’s fine. The fact that the DHS has a system that triggers some sort of reaction when someone tweets the words “destroy America” is perfectly sensible. (Even if it is a bit much to assume anyone will tweet about that if they intend doing it.)

But how can that phrase trigger a bureaucratic process that results in people being caged and deported, without any possibility of common sense intervention once that algorithm is triggered? It seems that no decision-making human entered the process, other than to verify that Leigh had in fact written the tweet, and as a matter of pure syntax, it could be interpreted as a statement of intent. I once read a science fiction story set in a world like that, where computers decided who was guilty and innocent based on algorithmic probabilities and (mis)interpretations of statements. It was scary, but laughable. Humans would never introduce such a system, right? Right?

As a matter of national security, this doesn’t look good. Making people from other countries afraid of talking about (or even mentioning the word) America will not serve long term security objectives, or the US national interest. Hearts and minds won’t be won when you can’t even discuss your feelings about a place.

Plus, I wonder if policymakers have considered what happens if other countries start following the US lead. What will the US reaction when its citizens are getting detained and deported all over the world for bad jokes, expressions, and political opinions they once expressed on Facebook?

The weird thing is that the story of Leigh and Emily is probably considered a success story for the social media monitors in the DHS. Threat detected. Threat neutralized. High fives.

Anyway, I’ve been careful as I typed this, hopefully careful enough to not get a detour to secondary screening next time I visit my friends in the states. In US First Amendment-speak, I’ve been feeling a “chiling effect.” I hope common sense prevails and the incident with Leigh and Emily is not a picture of our future. Now if you’ll excuse me, I’m off to destroy a bag of Taytos.

    Would it not save a lot of time, money and paperwork if they just automated the system to tweet the people they’d determined to be a threat and said:

    “Dear tweeter, you are now on our watch list, please don’t bother coming to America as you will be questioned, jailed & subsequently deported”

      Ah.. I was advised not to when I was setting up my MySpace account, back before Facebook and Twitter came on the scene..
      It seemed a bit paranoid at the time, but then I just used my nickname which my friends call me anyway.. But with twitter I don’t even use that – simply because I use it for accessing more public forums like this.. Like I explained to someone earlier – when it comes to expressing an opionion online it’s better to be mindful of who may be looking at it..

      Hi Shanti – makes no odds if you give your real name; the chances are your man updated twitter on his phone, so the tweet was tied to a phone number. The DHS have access to all UK Phone Databases, so it’s very simple to track the accused! That’s why I still use a “dumb phone”.

    You’ve got to ask. a) why are they wasting their time monitoring a service that has only 100m users worldwide? and b) if they were that much of a threat, how were they allowed board a flight and arrive in the US of A? Doesn’t add up.

    What bothers me is that this situation concerned one Irish Citizen and who the hell gave the US the right to monitor social network traffic in other countries. Last time I checked we were the Republic of Ireland. Never was pushed about visiting the States, and as someone posted earlier “scratches America off list of places to go”.

    I think that’s what you call hyper-vigilence gone wrong. I have vivid memories of having a Panic attack in Shannon airport. In hindsight, was it because I didn’t approve of the war in Iraq (which should never have happened) or was it an admin error? I will probably never know.

      Well Mark, you pretty much nailed it. As an American and a former military man, I can tell you it’s gone out of control. The Military Industrial complex as you mentioned, does exist in a verifiable form. I would suggest all those people who gave thumbs down, and even those who didn’t, to have a nice little read of “Confessions of an economic hit man” by John Perkins. I would say more than a few people would get the shock of their life and indeed see the exact same scenarios playing out in Dublin right now.

    People should target Discover America, the US Tourist board, with requests that their colleagues in Homeland Security exercise a bit of cop on. Maybe set up a petition/boycott.

    After all, it can’t make their job of attracting tourists to the US any easier when jobsworths are behaving like those ones in LAX.

    Seriously, do you intelligent people believe this? Article, has so many holes in it it’s like a cheese grater. A) do you enter your passport number into twitter? If not then the armed welcome reception better be watching out for everyone with the same name as you…could be confusing
    B) if they were a threat they would be imprisoned, not sent home. If deemed safe then they would be allowed to stay.
    C) no decision making human entered the process other than to verify that Leigh wrote the post? Really? Computers are allowed to decide the deployment of armed response units?

      Sanctimonious, patronising and plain old wrong Larry!

      A) His name is Leigh Van Bryan – how many Irish or UK Passport holders have this name? Easy to spot him.
      Also, he probably used twitter on his smartphone, therefore the account is tied to a phone number – the UK & US have sharing agreements in place for mobile phone number database registers. If he updated from a PC, then UK ISP Databases are also shared with the DHS.
      B) They were taken to secondary detention. Once this happens, you ain’t getting in. Secondary detention will decide what your fate is (guantanamo/US Trial/Sent home). They were obviously classified as not being an immediate danger, but their fate was sealed when they went to secondary.
      C) You are obviously not as intelligent as you like to think – I sell the kind of systems that the US are using to the British Government. They track every single passenger from check-in right to your destination. And yes, US DHS, CIA, ATF, FBI et all use computerised systems to deploy resources to “high-risk” areas.

      There’s a great research tool called the internet, we probably won’t have it for much longer, so I suggest you enlighten yourself there

      Daniel, I wasn’t trying to make a statement about how intelligent I am, more that I’m sceptical of the story details. However after further research I admit I don’t have too much grounds for the scepticism as it’s quite widely reported.

      Fair enough, if your selling this computer system the it seems you know more on the topic than I do.

      But I will make one further point, this story was broken by the Sun and Daily Mail and every major news source that features it is certain to quote that in order to distance themselves from any liberal use of the truth in the story details. Which was my original point, (granted I somehow managed to put in a very cheeky and argumentative manner) the story sounds a little bit soap opera.

    It would honestly put you off going to the states – which is a real pity, as they seem to choose the humans with least humanity from their number to be be the first people you meet on arrival.

    I was on a flight to Florida some years back, crammed with families going to Disney World. On arrival one family with young children were taken aside, treated in a very rude and unfriendly way (kids crying etc), and questioned by a series of quite threatening people. What marked them out? They had two small kids hurls – the wee tiny ones, for toddlers – in their luggage. Eventually, after a couple of unpleasant hours, the ‘weapons’ were confiscated and they were allowed in.

    It was trivial in the great scheme of things but quite frightening not just for the poor family immediately involved, but for all the people watching them being bundled away, many of whom were trying to explain to the other immigration people what a hurl was.

    Overreliance on computers and failure of human intelligence were the reason why 9/11 occurred. I do not think the U.S. government has learned any lesson from the tragedy. The more sophisticated the computers became, the less sophisticated the human intelligence became — and thus incidents like this that distract from real counter-terror work while also costing the American taxpayers more unnecessary money in this time of massive deficits.

    What also makes me wonder is how the DHS gets to decide whose Twitter handles belong to whom. Presumably they have never subpoenaed Twitter for user records, they simply made a connection between Twitter handles and possibly the profile photos, and the travellers. Given that many people make up fake Twitter handles, sometimes even impersonating others as parodies, and also given that there are many people with same or similar names and Twitter handles, the rate of false positives can be astounding, and many of them are probably simply unreported in the media.

    The arguments often used by the U.S. federal government is that the Constitution does not apply to those who have not yet been legally admitted to the U.S. by the CBP immigration inspectors. In this case, the immigration inspector did not exclude them — and this happened only after the fact at the customs inspection area. The moment the U.S. immigration inspector stamped their passport they are technically under the protection of the U.S. Constitution and associated due process. What makes this case murkier is the use of the Visa Waiver Pilot Program (VWPP, I-94W). Had they have a B-1/B-2 visa from the U.S. consulate, they could have had a better outcome. Unfortunately the VWPP requires tourists to waive all rights of appeal and all due process. Nevertheless, this case could prove to be interesting if the travellers choose to pursue a civil action outside the immigration system.

    The question raises how did the government link these twitter account to a real person while most people often use aliases? Yes, in this case the name of the twitter account is his real name but mostly it wont. What about other people with the same name? Overall one has to ask if twitter is not handing over personal information to the US government. It seems most likely that it does.
