The police in Watertown responded magnificently. But the most brilliant strategic move gets little notice from the press.
For about sixteen hours, hundreds of law officers, FBI agents, helicopters, and satellites scoured a relatively tiny area of Boston suburbs for one wounded terrorist. At the same time, they kept the public relatively safe, off the streets, and out of the way of their manhunt.
**But they didnât find their man. **
By seven o’clock, Col. Timothy Alben admitted they didnât know where Dzhokar Tsarnaev was. They believed he was still in the Greater Boston area, but they couldnât know for sure.
So authorities lifted the âshelter in placeâ request, allowing people to leave their homes with a powerful admonition: remain diligent.
Col. Alben made clear that there was no âall clear.â The world is a dangerous place, but Watertown, Massachusetts was beyond dangerous. Somewhere in that quiet neighborhood lurked a dangerous, desperate, wounded animal who knew how to shoot a gun, build a bomb, and throw a grenade. Tsarnaev had means and motive to kill anyone he encountered, and Col. Alben warned people not to give Tsarnaev the opportunity.
Lifting âShelter in Placeâ Led To Tsarnaevâs LIve Capture #
Malcolm Gladwell wrote about the human brainâs âthin-slicingâ ability in Blink. Experts can spot tiny anomalies that technology, to date, cannot.
We often think of experts as highly trained, long experienced professionals. In truth, though, weâre all experts on something, and David Hanneberry is the worldâs leading authority on the boat in his backyard.
Hanneberryâs mind had mapped every bulge, roll, and slack of the tarp covering the boat, which his step son described as Hanneberryâs greatest love, after his wife. When Hanneberryâs eye glimpsed a little flap of the canvas, he knew immediately something was wrong.
That one little ripple of canvas, which no algorithm on the worldâs most powerful computer could have detected, led to a bigger problem in Hanneberryâs mind: blood where blood shouldnât be.No doubt the blood lit up Hanneberryâs amygdala, the little almond-shaped nodes in the brainâs limbic system that triggers the flight or fight or freeze response.
Alert, curious, and cautious, Hanneberry spotted a cut line that held the canvas in place. Not torn or worn through, but cut clean with a knife.
He lifted the canvas and exposed the wrong of all wrongs: bleeding man in his beloved boat.
The Limits of Technology and The Power of People #
Had the âshelter in placeâ ordered remained in effect, itâs very possible that Tsarnaev would have died in David Hanneberryâs boat. All the helicopters and algorithms never would have told authorities that the canvas was flapping wrong. Big data didnât know how that canvas was supposed to flap; only Hanneberryâs brain knew that.
By lifting âshelter in place,â the police exponentially increased the computing power available to spot something wrong. It worked. Keeping people off the street was a great tactical move. Lifting the order when they did seemed to be perfect timing.
I doubt the police lifted the order to increase the number of eyes searching for Tsarnaev. But it worked brilliantly. And we now know the real power of crowd sourcing, thin-slicing, and the human brain.
