When crowdsourcing goes wrong: Reddit, Boston and missing student Sunil Tripathi

Reddit's initial hunt to find the Boston bombers devolved rapidly into a sort of "racist Where's Wally", profiling – racially and otherwise – scores of innocent people.

Update, 20 April: The two suspects for the bombing have been identified as Tamerlan and Dzhokhar Tsarnaev. The former was killed in a gunfight with police in the early hours of 19 April, while the latter was arrested and is now in custody. Sunil Tripathi was found dead on 24 April.

 

 

 

 

 

 

 

 

On 16 March, Sunil Tripathi, a student at Brown University in Providence, Rhode Island, went missing, leaving behind a cryptic note. His whereabouts are still unknown, but for a brief moment, it looked like he was involved in far bigger things. His name turned up on the Boston Police Department's scanner early this morning, suddenly and without warning. We now know that BPD was mistaken: according to NBC and the Associated Press, the suspects are migrants from an area of Russia near Chechnya. But that didn't stop a lot of people getting very excited.

The BPD was chasing two men who had held up a 7/11, shot and killed a police officer, and then headed west, apparently hurling explosives out of the window of the stolen SUV they were driving. As the chase continued, it seemed more and more likely that the men must be related to the Boston Marathon bombing, and at 7:20am BST the Boston Globe confirmed it: one suspect had been taken into custody. That man, they now report, is dead. The second remains at large.

But it's not quite true to say that Sunil Tripathi's name first came up in this startlingly new context on the BPD scanner. Because Reddit "called it" first.

Late last night, Redditor pizzatime linked to reports of Tripathi's disappearance, asking "Is missing student Sunil Tripathi Marathon Bomber #2?". At that time, the FBI had just released photos of two suspects, neither of whom had appeared on any of Reddit's crowdsourced hunts for the bomber. But pizzatime noticed that one of them bore a resemblance to Tripathi, and posted accordingly.

 

 

 

Reddit had set themselves the task of finding a needle in a haystack, but failed to take account of the fact that they had no way to tell for certain whether they'd found a needle or a needle-like piece of hay. The initial hunt to find the bombers devolved rapidly into a sort of "racist Where's Wally", profiling – racially and otherwise – scores of innocent people.

It's hard to be certain of the provenance, but that crowdsourcing (along with 4Chan's who did much the same thing) certainly led to images stripped of their context being passed around as though they were confirmed, and probably had a hand in the New York Post smearing two innocent men on their front page. And now it looks like it smeared Tripathi, too.

But really, the crowdsourced hunt for the bomber should be split into two acts. The first, finding suspicious-looking people in photos of the marathon, was always going to end in innocents' reputations being destroyed. With no method of confirmation, few feet on the ground and a wealth of opportunity for false positives, Reddit was abysmally suited for the task, and it failed abjectly.

But once the photos of the suspects were released, it had more chance of being useful. "Do you know this man?" is the archetypal example crowdsourcing. Wanted posters have been used for over 130 years, and we've got a pretty good hang on how they work by now: you need to find someone, so you show their face to as many people as possible. Tripathi looked like the second bomber, and so his name was linked. But then Reddit took it further.

The crowdsourcing part of wanted posters is about making sure as many people as possible see the picture. It is emphatically not about making sure any allegations resulting from the picture are made public. That's not crowdsourcing, it's just speculating; there is little advantage in getting the crowd involved at that point, and the major downside that someone's life might be ruined based on who they look like.

Tripathi wasn't the bomber. He just looked like him. How his name ended up with the Boston Police Department remains unclear, but it is clear that he is not a suspect. Where he is remains an open question, but maybe one Reddit should steer clear of. The world hasn't changed that much.

Emmanuel Macron can win - but so can Marine Le Pen

Macron is the frontrunner, but he remains vulnerable to an upset. 

French presidential candidate Emmanuel Macron is campaigning in the sixth largest French city aka London today. He’s feeling buoyed by polls showing not only that he is consolidating his second place but that the voters who have put him there are increasingly comfortable in their choice

But he’ll also be getting nervous that those same polls show Marine Le Pen increasing her second round performance a little against both him and François Fillon, the troubled centre-right candidate. Her slight increase, coming off the back of riots after the brutal arrest of a 22-year-old black man and Macron’s critical comments about the French empire in Algeria is a reminder of two things: firstly the potential for domestic crisis or terror attack to hand Le Pen a late and decisive advantage.  Secondly that Macron has not been doing politics all that long and the chance of a late implosion on his part cannot be ruled out either.

That many of his voters are former supporters of either Fillon or the Socialist Party “on holiday” means that he is vulnerable should Fillon discover a sense of shame – highly unlikely but not impossible either – and quit in favour of a centre-right candidate not mired in scandal. And if Benoît Hamon does a deal with Jean-Luc Mélenchon – slightly more likely that Fillon developing a sense of shame but still unlikely – then he could be shut out of the second round entirely.

What does that all mean? As far as Britain is concerned, a Macron or Fillon presidency means the same thing: a French government that will not be keen on an easy exit for the UK and one that is considerably less anti-Russian than François Hollande’s. But the real disruption may be in the PR battle as far as who gets the blame if Theresa May muffs Brexit is concerned.

As I’ve written before, the PM doesn’t like to feed the beast as far as the British news cycle and the press is concerned. She hasn’t cultivated many friends in the press and much of the traditional rightwing echo chamber, from the press to big business, is hostile to her. While Labour is led from its leftmost flank, that doesn’t much matter. But if in the blame game for Brexit, May is facing against an attractive, international centrist who shares much of the prejudices of May’s British critics, the hope that the blame for a bad deal will be placed solely on the shoulders of the EU27 may turn out to be a thin hope indeed.

Implausible? Don’t forget that people already think that Germany is led by a tough operator who gets what she wants, and think less of David Cameron for being regularly outmanoeuvered by her – at least, that’s how they see it. Don’t rule out difficulties for May if she is seen to be victim to the same thing from a resurgent France.
